This part of the instruction manual contains all the specific information on how to
operate the optical source modules WDM8xxxx, C81xxxx and LS8xxxx. A general
description is followed by explanations of how to operate the unit manually. You will
also find complete information about remote control via the IEEE 488 computer
interface.
Attention
This manual contains “WARNINGS” and “ATTENTION” labels in this
form, to indicate personal danger or possible damage to equipment.
Please read these advises carefully!
NOTE
This manual also contains “NOTES” and “HINTS” written in this form.

1 General description of the optical source modules
1.1 Safety
Attention 
The modules ‘WDM8xxxx’ are class 1M laser sources.
Emitted wavelength: 1 single wavelength in the range 1454 nm …
1625 nm, according to ordered wavelength.
Emitted optical power: up to 50 mW, according to ordered output
power! Numerical aperture of the beam 0.11.
CAUTION – The use of optical instruments with these products will
increase eye hazard!!

Attention 
The laser modules supplied by Thorlabs are class 1M laser systems.
However, if you collimate or focus the laser beam you will create a
class 3R or class 3B laser system!
In that case additional safety measures have to be observed!
For the individual wavelength and output power see the certificate of
calibration supplied with the module!
Never switch on the output with no fiber connected and switch off
the output before disconnecting the fiber!
NOTE
The products are classified and labeled according to
IEC 60825-1/Am2 (2001).
If you need an additional aperture label according to CFR § 1040.10.g (5)
please use the adhesive labels delivered with the PRO8000 (-4) / 800 and
place them clearly visible for any possible user on your laser set-up!.
Two possible places for laser modules without and with modulation input
are shown below.
Without modulation input
(label 30 x 15 mm)
With modulation input
(label 20 x 15 mm)

PRO8000 (-4)/800 optical sources / page 3
Attention 
All statements regarding safety of operation and technical data in
this instruction manual will only apply when the unit is operated
correctly.
Before applying power to your PRO8000 (-4) / PRO800 system, make
sure that the protective conductor of the 3 conductor mains power
cord is correctly connected to the protective earth contact of the
socket outlet!
Improper grounding can cause electric shock with damages to your
health or even death!
Modules may only be installed or removed with the mainframe
switched off.
All modules must be fixed with all screws provided for this purpose.
Modules of the 8000 series must only be operated in the mainframe
PRO8000, PRO8000-4 or PRO800.
All modules must only be operated with duly shielded connection
cables.
Only with written consent from Thorlabs may changes to single
components be carried out or components not supplied by Thorlabs
be used.
This precision device is only dispatchable if duly packed into the
complete original packaging including the plastic form parts. If
necessary, ask for a replacement package.

Attention 
Mobile telephones, cellular phones or other radio transmitters are
not to be used within the range of three meters of this unit since the
electromagnetic field intensity may then exceed the maximum
allowed disturbance values according to EN 50 082-1.
The PRO8000 (-4) / PRO800 must not be operated in explosion
endangered environments.
