Warning: The Koheras BOOSTIK amplifiers are rated as Class
3B and Class 4 laser devices. Before any operation is attempted,
ensure the notices within this manual and the hazard labels on the
product, are read, noted, and adhered to.
In addition, make sure to follow all safety recommendations listed
in the Koheras BOOSTIK Safety and Handling Information
document shipped with your amplifier. If in doubt, consult your
laser safety officer.
Warning: Not installing a door interlock may expose persons to
harmful laser emissions. The responsible party must ensure that
staff is properly trained in the safe operation of a Class 4 laser.
Note: DO NOT dispose of the packaging your amplifier was
shipped in. It is vital to keep it available for future shipping
requirements.
Reference documentation
The Koheras BOOSTIK is a module which is a component of a laser system. For further information regarding
Koheras modular system components refer to the following documentation
• Koheras ACOUSTIK User Manual V4
• Koheras BASIK User Manual V5
BEFORE OPERATING THIS DEVICE: READ and UNDERSTAND the information listed in the included document:
• Koheras BOOSTIK Laser Safety and Handling Information
The Koheras BOOSTIK is a compact fiber amplifier module for
low-noise, narrow-linewidth Koheras seed lasers. It operates in
the 1060-1075 nm or 1545-1565 nm wavelength range.
Depending on the variant, the amplifier is designed to extend
the output power of an associated seed laser to either 200
mW or 2 W output power. The amplifier achieves this while
preserving the seed laser’s ultra-low noise and narrow
linewidth optical output. BOOSTIK amplifier modules are
components of a laser system designed to be inserted into two
slots of a Koheras ACOUSTIK cabinet and coupled with
Koheras BASIK seed lasers. For slot installation, the module
includes a slot alignment pin hole to ensure the electrical
connector mates correctly. Additionally, a front panel (not
shown) can be fastened to the cabinet front face. The module
can also be implemented as a component in custom laser
systems. For these applications, NKT Photonics’ SDK is
available to integrate the module with the system control
platform.

Custom stand-alone installation
For simple custom systems, the amplifier module must be placed on a
level and stable surface. The module can be bolted for example, to a
table using a custom mounting bracket (not included) attached to the
side of the module.
Cooling
The amplifier module generates substantial heat during operation. For
proper operation, you must ensure that the heat is dissipated by
providing an efficient thermal path from either the rear panel or the
side panel as illustrated. (Cooling blocks or heat sinks are not included.)
Connect the module to a CONTROL PC
The amplifier module is designed as a component in a laser system that includes safety and communication
functionality. The module can be operated using NKT Photonics CONTROL application installed on a PC. To
establish communication between a CONTROL PC and the amplifier, first make the following connections to the
appropriate main electrical interface:
• 12 VDC power and ground
• A door switch safety interlock circuit that complies with applicable safety regulations.
• An RS-485 data connection between a PC and the amplifier.
Note: Follow these installation rules:
• Allow for proper ventilation and cable access.
• Do not store or place anything on the top panel of the amplifier.
• Ensure the ambient operating temperature and humidity is
stable as stated in the “Amplifier Specifications”. Avoid placing
the amplifier near sources that could cause temperature
fluctuations.
• The surface the amplifier is placed on, must be free of vibration
or mechanical shocks.
Optional RS-485 adapter kit
For system integration and testing, the amplifier module can be provided with an
optional kit that provides the necessary power, interlock and communications to
operate a stand-alone module. To use the kit, follow the steps below and refer to
the adapter description “RS-485 Adapter” on page 8:
a. Connect the BOOSTIK interface board to the main interface 30 pin C/3
connector on the rear panel of the module.
b. Using the IDC 16 pin to DB-15 ribbon cable, connect the NKT Photonics RS-485
adapter to the 16 pin main interface connector on the BASIK interface board.
c. Connect the RS-485 adapter to your PC using the USB-A to USB-B cable.
d. Connect a door safety switch circuit using the two-pin LEMO connector to the
interlock port of the RS-485 connector.
e. To power on the module, connect the power supply to the RS-485 adapter
power jack and AC mains.
Warning: When using the adapter kit, DO NOT CONNECT a laser seed source and ONLY use the adapter kit for
temporary test purposes. Connecting the BOOSTIK to a laser seed source along with an RS-485 adapter is UNSAFE
and contravenes IEC standard 60825-1 Safety of Laser Products.

RS-485 Adapteri
An RS-485 adapter kit can be provided separately. The adapter functions include:
• Input for DC power
• USB to RS-485 communication ports
• Interlock connections and defeater (jumper)
• Status LEDs
The adapter connects and converts the module’s RS-485 communication signals to USB. The USB level signals
can then be connected to a CONTROL PC or a custom control platform using the SDK. The adapter connects to
the module using a 16 pin ribbon cable with a male DB-15 connector. For USB connectivity the adapter is
equipped with a B-type USB port that can typically connect to a PC using a standard Type A to Type B USB cable.
The adapter also provides a two pole power input socket to connect with an external power supply. The
connected DC supply powers the adapter and also provides power to the module through the DB-15 connector
and ribbon cable.
To connect the module’s interlock pins to a door switch, the adapter is equipped with a standard 2 pin LEMO
connector. The LEMO connector is connected internally to the adapter’s DB-15 connector and the interlock pins
on the module’s main interface connector through the ribbon cable.
i. If not included, A connector kit with the adapter is available by contacting NKT Photonics support - see “Support” on page 7
Warning: When using the adapter kit, DO NOT CONNECT a laser seed source and ONLY use the adapter kit for
temporary test purposes. Connecting the BOOSTIK to a laser seed source along with an RS-485 adapter is UNSAFE
and contravenes IEC standard 60825-1 Safety of Laser Products.
