1 Introduction
The modular Laser-Induced Breakdown Spectroscopy (LIBS) system described in this User’s Manual is
designed to be a highly versatile product for use by research scientists, application engineers and OEMs.
Essentially a “LIBS system building block”, the LIBS-6 and LIBS-8 modules may be used together with a
variety of Q-switched Nd:YAG lasers and optical spectrometers to form a customised, modular LIBS
system tailored to suit the requirements of a specific application or experimental research project. The
LIBS modules remove the need for the research scientist or application engineer to design and construct
their own laser focussing optics and plasma light collection optics by combining these features into a
compact, integrated and easy to use device. An optional imaging kit may be added to the LIBS module,
increasing further its functionality and versatility.
The modular LIBS system described in this User’s Manual comprises the following main components: a
LIBS-6 module, two AP-Bernoulli adaptor platforms (one for 1064 nm laser configuration and one for
266 nm laser configuration), a Litron Bernoulli double-pulse dual wavelength (1064 nm and 266 nm)
pulsed Nd:YAG laser, an XYZ-750 modular sample chamber with computer-controlled 3-axis translation
stage, and a Catalina Scientific EMU-120/65 echelle spectrograph equipped with a Raptor Photonics
EMCCD camera.
This User’s Manual provides the necessary information needed to configure the LIBS equipment and
operate the equipment safely. It is assumed that the user will be familiar with the safety issues arising
from the use of high-power lasers and will have preferably been trained in the safe use of high-power
(Class 4) laser products.
2 Safety
2.1 Laser radiation
The modular LIBS system utilises a high-power Q-switched Nd:YAG laser (Class 4) and so it is
imperative the equipment is operated only by suitably trained and experienced persons who are fully
aware of the hazards inherent to this type of high-power laser equipment. It is imperative also that, prior
to using the equipment, an appropriate risk assessment is conducted in such a way as to take account of
the proposed use of the equipment, the environment in which the equipment is to be operated, and how its
use may affect people who are not directly involved with the use of the equipment.
Example of a laser warning product label
The modular LIBS system is designed to meet the laser safety requirements of the relevant European
standards (BS EN 60825) and USA standards (ANSI Z136.1). Although the modular LIBS system is
supplied with a sample chamber which provides adequate containment of the laser radiation to Class 1
Accessible Emission Limits, it is possible for the user to operate the LIBS equipment without the sample
chamber (ie. operation in “open beam” mode as may be required for certain types of experiment).
Accordingly, it is necessary to consider the modular LIBS system to be Class 4 Laser Products and so,
by definition, the equipment poses a risk of personal injury (eye, skin injury) and poses a fire risk. As
with all Class 4 laser products, appropriate safety precautions must be taken as identified via a suitable

© 1998 - 2022 Applied Photonics Ltd Page 4 of 42
risk assessment conducted by the user in consultation with a suitably qualified and experienced Laser
Safety Officer.
The most significant hazard relating to exposure of personnel to the laser radiation is eye injury since
direct or scattered laser radiation produced by the equipment can cause serious and permanent injury to
the eyes including blindness - such injury may be instantaneous. Precautions must be taken to avoid
exposure of personnel to hazardous levels of laser radiation. Such precautions may include the setting up
of a temporary or permanent laser controlled area (e.g. a laser laboratory). Other measures may also be
necessary, as determined by appropriate and thorough assessment of the risks (ie. a risk assessment)
conducted by the personnel responsible for the safe use of the laser equipment. Consult the User’s
Manual supplied with the laser for further guidance on the safe use of the laser.
The door of the sample chamber is equipped with a dual electrical interlock switch which is designed to
prevent activation of the laser unless the door is fully closed. The door interlock switch is electrically
connected to the “Interlock In/Out” port on the LIBS module via the 9-pin connector located directly
above the laser aperture. The “Interlock In/Out” port connects with the Interlock Interface Unit (using the
supplied lead) which in turn is connected to the interlock circuits of the laser power supply. This is
discussed in more detail later in this User’s Manual.
Interlock Interface Unit
Removal of the sample chamber from the LIBS-6 module, or disconnection of the Interlock In/Out lead,
will also activate the interlock (ie. prevent activation of the laser). The Interlock Interface Unit is
equipped with an Interlock Override facility (a keyswitch) which allows the interlock to be disabled so
that the LIBS system may be used without a sample chamber (ie. “open beam” mode). In view of this,
the modular LIBS system must be categorised as a Class 4 laser product since, by design, the product
may be used in such a way that the laser beam is not contained (ie. “open beam” mode of operation).If,
however, the sample chamber is correctly fitted to the LIBS-6 module and the Interlock Override
keyswitch is switched off and the key removed, then the laser radiation is adequately contained to Class 1
Accessible Emission Limits by the design of the hardware.

IMPORTANT
•READ and UNDERSTAND both this User’s Manual and the instructions provided by the
manufacturer of the laser before operating the LIBS equipment.
•ENSURE that an appropriate risk assessment has been conducted to establish whether or not the
laser safety windows fitted to the modular sample chambers provide adequate protection against
exposure to laser radiation for the specific laser you intend to use with the LIBS equipment.
For advice on this matter, consult your Laser Safety Officer and/or Applied Photonics Ltd.
•ONLY suitably qualified and authorised persons should activate the Interlock Override keyswitch.
The key should be removed from the keyswitch and held by the Laser Safety Officer when this
feature is not required.
•ALWAYS use appropriate laser safety protective eyewear when operating the LIBS equipment in
“open-beam” configuration –you should seek advice from your Laser Safety Officer on this
matter.
•ALWAYS switch the laser off when not in use and remove the key from the keyswitch of the laser
power supply to prevent unauthorised activation.
•ALWAYS thoroughly inspect the LIBS equipment for damage prior to use. Particular attention
should be given to the laser safety windows and the laser safety interlock system, which should be
tested each time the equipment is used.
•NEVER allow unauthorised and/or untrained persons to operate the LIBS equipment.
•NEVER operate the LIBS equipment in areas where explosive gas mixtures may be present.
•NEVER operate the LIBS equipment with any access cover, panel, or protective window
removed.
•NEVER place inside the sample chamber flammable liquids or any other material which may give
rise to flammable / explosive gas mixtures. Activation of the laser under these conditions could
result in an explosion leading to severe personal injury and/or fire hazard. Remember that the
laser-induced plasma is a source of ignition.
•NEVER point the LIBS laser beam at a person (even with laser switched off), especially towards
the eyes, even if the person is wearing laser safety eyewear. The laser should be considered
“active” unless the laser power supply is deactivated.
•NOTE that the transparent acrylic nozzle aperture of the LIBS-6 module does not provide any
protection to the user against exposure to direct or scattered laser radiation. The function of the
nozzle aperture is described later in this User’s Manual.

R L6 at 1064 nm indicates a protection level of maximum spectral transmittance of 10-6 at 1064 nm for a
pulsed laser of pulse length 10-9 –10-7 seconds (i.e. a Q-switched laser).
The laser safety windows used in Applied Photonics Ltd’s range of modular sample chambers provide
adequate protection against scattered laser light of wavelength 1064 nm, 355 nm and 266 nm such that
Class 1 Accessible Emission Limits are met if the sample chamber is used correctly and laser pulse
energies are not excessively high (i.e. typically less than 300 mJ with a 5 - 10 ns pulse length). Note that
the protective windows are NOT suitable for use with a 532 nm laser. Given that the LIBS-6 (and LIBS-
8) modules may be used with a variety of lasers, it is the responsibility of the user to conduct a risk
assessment to establish whether or not the laser safety windows provide adequate protection for the
particular laser being used. If in any doubt, you should consult your Laser Safety Officer and/or Applied
Photonics Ltd for advice on this matter.
Warning –the Applied Photonics Ltd modular sample chambers are designed specifically for use
with our LIBS-6 / LIBS-8 integrated LIBS modules and our LIBSCAN range of products and
should not be used with any other laser device or product. If in doubt, seek advice from the
manufacturer, Applied Photonics Ltd.

2.3 Electrical
The LIBS-6 integrated LIBS module, the XYZ-750 sample chamber and the Raptor Photonics EMCCD
camera contain electrical circuits operating at 12 VDC at a maximum current of 2.5 Amps. Accordingly,
they pose no electric shock risk. The laser head and associated power supply, however, contain electrical
circuits operating at potentially lethal voltage and current levels. Consult the manufacturer’s User
Manual supplied with the laser for further guidance on the safe use and routine maintenance of the laser.

Camera specifications:
•1/3-inch CMOS colour sensor 2.5 MP (1956 x 1266)
•Adjustable focus (approx. 20 mm to infinity –factory set during testing of LIBS system)
•Lens: f = 12 mm, f/1.8
•12 VDC @ 1 A
The LIBS modules have the following features:
•Plasma light collection lens array (six channels) having a relatively large depth-of-field to allow efficient light
collection even when the plasma position varies by approximately ±3 mm along the optic axis of laser beam.
•3-lens laser beam expander with adjustable focus (adjustment of focal plane made by rotating the brass beam
expander lens holder via the cut-way in the laser beam tube –adjustment range of approx. 14 mm).
•Adjustable nozzle aperture which provides a convenient means of setting the distance to the sample surface
(adjustment range of approx. 14 mm). The nozzle aperture may be removed if this feature is not required.
•Gas-purge port (accepts 4 mm flexible nylon tube) which may be used to feed inert gas (e.g. argon, helium, nitrogen)
to the sample surface. To ensure purge gas is directed to the sample, it is necessary to fit the nozzle aperture.
•Optional miniature CMOS colour video camera with array of dimmable high-brightness white LEDs for illuminating
sample surface.
•Laser safety interlock with keyswitch operated override facility (via the Interlock Interface Unit).
•Compatible with the Applied Photonics Ltd (APL) range of modular sample chambers.

The optical configuration used in the LIBS-6 (and LIBS-8) modules is illustrated schematically in the
following diagram. The laser beam expander consists of three lenses and is used to provide a tightly
focussed laser beam at nominally 100 mm from the aperture of the beam expander. The optical design is
specific to the make and model of laser which the LIBS-6 or LIBS-8 module is to be used with –this is
specified at the time of ordering of the LIBS module. For this configuration, two LIBS-6 modules are
provided –one for use with a 1064 nm laser beam and the other for use with a 266 nm laser beam. These
two LIBS-6 modules differ in the design of the beam expander and so it is important that the correct one
is used according to the configuration (i.e. 1064 nm or 266 nm output beam) of the Bernoulli laser. The
brass tubular piece which houses the beam expander lenses is threaded (1 mm pitch thread) so that
rotating it causes the focal plane of the laser beam to move. The design allows for approximately ±7 mm
of adjustment, as illustrated in the following diagrams. The plasma light collection optics are angled at
approx. 17 degrees and are designed to collect light from the region in space defined in the following
diagram. The transparent nozzle aperture is threaded so that rotation causes it to move along the optic
axis of the laser beam –range of travel is approximately ±7 mm. The nozzle aperture may be removed
from the body of the LIBS-6 or LIBS-8 module by unscrewing further or by removing the threaded black
acrylic piece it screws into by unscrewing the four M4 cap head screws. The main purpose of the
transparent nozzle aperture is to provide a convenient means of setting the distance to the sample surface.
The nozzle aperture also provides containment of the purge gas, if used, to ensure the sample surface and
laser-induced plasma region are effectively purged of atmospheric air. Physical protection for the laser
beam optics and plasma light collection optics (and imaging camera if fitted) is also provided by the
nozzle aperture.

3.3 Right-angle mirror modules
This configuration is supplied with two Mirror Modules –one for 1064 nm laser configuration and one
for 266 nm laser configuration. Further details on how to use these components are provided later in this
User’s Manual.
Mirror Module (1064 nm)
Internal view of Mirror Module showing laser beam path
The Mirror Module provides precise alignment of the laser beam for the LIBS-6 module which is
attached to the output side of the mirror module. Optical alignment is carried out at APL during final
assembly of the LIBS equipment and so there should be no need for the user to adjust the internal mirror
assembly. The Mirror Module, Adaptor Platform and LIBS-6 module each include dowel pin fittings so
that precise optical alignment is maintained on removing and refitting these components. If you suspect
that the optical alignment of the laser beam has been compromised, contact APL for advice before
attempting to realign the optics.
3.4 Adaptor Platforms
Two Adaptor Platforms are included with this configuration –one for 1064 nm laser configuration and
the other for 266 nm laser configuration as illustrated below.
Adaptor Platform for 1064 nm laser configuration
Adaptor Platform for 266 nm laser configuration
The purpose of the Adaptor Platform is to provide a rigid platform on which to attach the laser head and
to provide correct positioning of the laser head so that optical alignment with the Mirror Module and the
LIBS-6 module is maintained. Mechanical alignment stops are integrated with the design of the Adaptor
Platform for this purpose. Further details on how to use these components are provided later in this
User’s Manual.

3.5 Litron Bernoulli double-pulse, dual wavelength (1064 & 266 nm) laser
The Bernoulli laser is essentially two laser heads combined into one unit. The laser may be operated in
single pulse or double pulse mode. Control of the laser including choosing single pulse or double pulse
output is controlled via the LIBSoft software. In double pulse mode, interpulse delay times are set within
the LIBSoft software (see LIBSoft User’s Manual for full details). The laser may be configured for either
1064 nm or 266 nm output –the procedure for this is explained later in this User’s Manual.

The XYZ-750 computer-controlled sample chamber is one of APL’s range of modular sample chambers
designed for use with APL’s modular LIBS systems. The XYZ-750 requires LIBSoft software to operate
as it has no manual control of the three stages.
XYZ-750 computer-controlled, modular sample chamber
The XYZ-750 has the following features:
•3-axis motorised and computer-controlled translation stages each with 75 mm travel
•Precision ball-screw design which reduces rotational friction and virtually eliminates mechanical backlash
•Heavy-duty linear rail bearings (two rails per stage)
•Translation stage linear resolution of 1 µm
•Sample table breadboard with array of M6 tapped holes on 25 mm centres (5 kg load rating)
•Hinged door with magnetic catch and dual redundant electrical safety interlock
•Laser protective windows on two sides and hinged door
•Fume extraction port with internal flexible tube (external fume extraction system not included)
•Internal lighting
•External dimensions of approx. 330 x 360 x 430 mm. Weight approx. 21 kg
3.9 LIBSoft software
APL’s LIBSoft software has been designed specifically for APL’s range of modular LIBS systems.
LIBSoft can control the various hardware components of the LIBS system including the laser, the
spectrograph, the delay generator and the sample chamber translation stages. LIBSoft also controls data
acquisition offering a number of features specifically developed for LIBS. LIBSoft has some data
processing features including emission line identification and tools for constructing calibration plots for
quantitative analysis. LIBSoft is continually being developed further to include more features and APL
offers free software upgrades to its customers for a period of two years. A detailed User’s Manual for
LIBSoft is supplied with the LIBS equipment.

4 Configuring the hardware
4.1 Introduction
For this particular configuration of LIBS equipment, two LIBS-6 modules are provided –one configured
for a 1064 nm laser beam and another configured for a 266 nm laser beam. The LIBS-6 modules are
attached to the laser head using an appropriate Adaptor Platform. For this configuration, two Adaptor
Platforms are provided –one for when the laser is configured for 1064 nm and another for when the laser
is configured for 266 nm. Additionally, two right-angle Mirror Modules are provided (one for 1064 nm
and another for 266 nm) which fit between the LIBS-6 module and the Adaptor Platform as illustrated in
the following diagram.
4.2 Configuring the Litron Bernoulli laser and fitting to the appropriate Adaptor Platform
The LIBS equipment may be operated with a laser beam wavelength of 1064 nm or 266 nm. The laser
head needs to be configured differently for each wavelength and so two Adaptor Platforms are included –
one for 1064 nm and one for 266 nm, as shown below.

The LIBS-6 modules and Mirror Modules are supplied fitted together as shown below. They may be
disconnected from each other but we recommend that they remain attached as two assemblies –one for
1064 nm and one for 266 nm. They are clearly labelled with the laser wavelength as shown below. It is
very important that the LIBS-6 module / Mirror Module assembly is correctly chosen to suit the laser
beam wavelength. Failure to do so will result in damage to the optical components and may also cause
damage to the laser head.
Note: Incorrect use of these components with regard to laser beam wavelength will void the warranty.

Select the Adaptor Platform, Mirror Module and LIBS-6 module which are each labelled 1064 nm.
Configure the Litron Bernoulli laser for 1064 nm operation as illustrated below.
Fit the laser head to the 1064 nm Adaptor Platform as shown in the following images:
Note: A video clip is available which shows how to fit the laser head to the Adaptor Platform.

To achieve correct optical alignment, ensure the body
of the laser head is in contact with the mechanical
alignment stops as shown in the above image

Four M6 cap head screws are used to attach the laser head
to the Adaptor Platform. It is more convenient to place
the laser head upside down on some foam and then offer
up the Adaptor Platform as shown above. The four M6
cap head screws should not be fully tightened at this time.
Prior to tightening the M6 screws, place the Adaptor
Platform on its side as shown above so that the laser is
resting on the mechanical alignment stops. This helps to
ensure the laser head is correctly positioned prior to
securing in place.

Refer to the LIBSoft software User’s Manual for further information. The Quick Setup Guides appended
to this User’s Manual should also be referred to.
After correctly fitting the laser head to the 1064 nm Adapt Platform, fit the 1064 nm LIBS-6 module /
Mirror Module to the XYZ-750 sample chamber as shown in the following images.
The LIBS-6 module / Mirror
Module assembly should be
carefully offered up to the sample
chamber so that it fully fits into the
top port of the sample chamber.
Care should be taken not to damage
the electrical connectors (9-pin D-
type). The four M5 cap head
screws located in the lid of the
sample chamber are used to secure
the LIBS-6 module to the sample
chamber. They are accessed from
inside the sample chamber. Do not
fully tighten these screws at this
time –they should be “finger tight”
only.
A video clip is available which
