GUIDE OVERVIEW
This product guide is intended to provide functional, operational and installation
information for the Koheras ACOUSTIK multi-channel laser system. The guide is
divided in 3 sections as follows:
• Koheras ACOUSTIK Description - introduces the modular laser system, its
functionality, interfaces and system variants.
• Installing the Laser – includes the details on how to install the laser system
and connect optional interfaces.
• Operating the Laser – provides information and procedures on how to
configure and control the modular laser system and its inserted modules.
Warning: Do not operate the laser before first reading and understanding all
warnings, cautions and handling information stated within the documents:

Warning: Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure.
BOOSTIK amplifiers If you have inserted a 2 W BOOSTIK laser amplifier into an BASIK, you need to
ensure Class 4 laser safety labeling is affixed to the system paneling. See
“system labeling update” on page 24.
Terminology This guide refers to the Koheras ACOUSTIK as the “laser system” or simply
“system”. The Koheras ACOUSTIK is built specifically to contain laser modules
within its slots as components of a multi-laser system. In specific cases where a
distinction is required, this guide will use the actual module names. Further, other
NKT Photonics literature may refer to the Koheras ACOUSTIK as a frame or
cabinet. These terms are one and the same as the term “system” within this
guide.
Target audience This guide is for technical personnel involved in the selection, planning and
deployment of lasers in laboratory and industrial settings. The guide assumes a
reasonable knowledge level of lasers, photonic principles and electrical interface
connectivity.

1 Description
The Koheras ACOUSTIK is a rack or table mounted 16 slot modular laser system
designed to integrate multiple Koheras BASIK fiber laser modules and optional
BOOSTIK amplifier modules (2 maximum). Modules slide into the system’s slots and
mate with a backplane electrical connector. Inserted BASIK modules require one slot
each and BOOSTIK modules occupy two slots. The ACOUSTIK includes a control
section that provides power, signaling
1
and data communications to all inserted
modules. The control section’s functionality includes:
• system controller – Provides overall management and operation of all
modules.
• DC Power – Supplies DC power to all inserted modules including an AC main
power ON/OFF switch.
• Safety – Interconnects the inserted modules with a single safety interlock
circuit including door and key switch control.
• Control interfaces – Serial USB or Ethernet connectivity connects a control
PC to all inserted modules and the system controller.
• Modulation and trigger I/O – External input and output ports for wavelength
and emission control of inserted modules.
• Status LEDs - Summary indicators for all inserted modules.
• Emission button – Enables emission for all inserted modules
Figure 1 ACOUSTIK front panel
Optical output BASIK modules only
Up to 16 BASIK modules can be inserted into the system. In a standard system, optical
output is distributed from each individual module using either FC/APC or SC/APC
connectors. Fiber distribution of up to 16 main outputs and 16 monitor outputs is
managed through mechanical means and fiber bend radius limits must be observed.

BASIK with BOOSTIK modules
Due to heat dissipation limitations, an ACOUSTIK laser system can only be operated
with a maximum of 2 BOOSTIK amplifier modules. Further, the amplifiers must be
installed in specific slots as described in
“Mechanical Installation” on page 29 .
When amplifier modules are needed, a full installation includes 2 BOOSTIK amplifiers
and 12 BASIK modules.
When paired with a BASIK laser module, a BOOSTIK module can extend the output
power of the system by up to 2 W. The the main output fiber from a Class 3B BASIK is
connected directly to the input of a BOOSTIK amplifier which then boosts the optical
power to a Class 4 rating at its optical output.
Multiplexed optical output
The Koheras ACOUSTIK system is specified with or without optical multiplexing.
Without multiplexing, the individual optical outputs of each module is employed.
When the multiplexed optical output feature is included, the optical output of inserted
modules is combined into a signal optical output on the rear panel of the laser. As this
is an advanced feature that requires a customized design, contact NKTP to discuss
your application suitability for the multiplexed option.
Note: BOOSTIK modules are not supported for use with the multiplexed output op-
tion.
Figure 2 Multiplexed optical output port
Slot configurations Table 13 of Appendix E shows the supported ACOUSTIK module configurations that
can be inserted into the system slots. Either one or two BOOSTIK modules can be
inserted in specific slots and all other available slots can be fitted with BASIK modules
as required. The system can be fitted from as little as one module to a full slot
configuration.
Note: Proper cooling of an ACOUSTIK system and its inserted modules must be
maintained and is described in the chapter
“Mechanical Installation” on page 29 .
Front and rear panels
Front panel Figure 3 shows the front panel of the ACOUSTIK laser system. The front panel
provides access to 16 slots. A single slot can house a Koheras BASIK module that
connects to a backplane connector. For Koheras BOOSTIK modules, two slots are
2

Front and rear panels
needed, however only the backplane connector in the right side slot connects to the
module’s rear panel electrical connector.
The front panel also incorporates controls and indicators for managing the inserted
modules. These include: status LED indicators, an emission button, a security and
interlock key switch, and an AC mains switch. To connect a management PC (with
CONTROL), a USB port is located on the upper right panel of the control section.
Figure 3 ACOUSTIK front panel layout - BASIK modules only
System slots
At the back of each slot, mounted on the system backplane, a female 30 pin C/3
connector connects to each module’s electrical connector. When a module is pushed
into the slot, the connectors are aligned by a hole in the rear panel of the module
which slides over an alignment pin projecting out from the backplane.
Note: BOOSTIK modules occupy two slots, but only connect to the C/3 connector of
the right
slot.

USB type B port
This is the system management port, use a USB cable to connect this port to a PC.
You can control the inserted modules using the NKT Photonics CONTROL
application.
Emission control button
Pressing the button enables or disables emission from all modules inserted and
ready in the system.
Key switch
The key switch must be ON to enable the interlock and permit emission. Remove the
key to prevent unauthorized laser operation.
AC mains switch
ON/OFF AC power switch that turns the system controller ON and supplies DC power
to all inserted modules.
Rack mounting flanges
The front panel includes flanges on each side for mounting the system onto a
standard 19 inch rack. For more information on installing the system, see
“Mechanical Installation” on page 29 .
Rear panel Figure 5 shows the rear panel connectors and part of the cooling fin array that
maintains the inserted modules at their optimum operational temperature.
The rear panel provides connectivity for control signals, safety interlock, accessories,
and AC mains.
