Miscellaneous
Power verification
This feature internally monitors the output power level from the fiber stage. If power
drops below a predefined level in relation to the measured pump current, laser
emission is automatically shut off.
Note: The slope is different for each individual laser as their emission efficiency var -
ies.
The feature prevents for example, the output power reaching its maximum value if
feedback disappears (unexpectedly) to the internal output power control function.
Miscellaneous
Safety
Warning: The lasers are rated as class 3a lasers and are therefore hazardous. Be -
fore turning on the laser, ensure to read and understand all safety statements of
the document:
Koheras ADJUSTIK Safety, Handling and Regulatory Information
A paper copy of this document is included with your laser. If you do not have access
it, you can download a copy from:

Optical interface
The laser has two optical outputs (marked with an ‘A’ and a ‘B’ on the front of the
module). Assignment of the output type depends on the laser configuration ordered
from the factory. The optical outputs are assigned as either:
•
Main – this is the laser’s primary optical output (typically Class 3B) near
which, a laser aperture label is affixed.
– or –
•
Monitor – this is a low power output intended for monitoring purpose only.
The output is classified as a laser CLASS 1 and therefore it does not require a
laser aperture label.
Contact NKTP support for information on how the laser’s optical ports are assigned.

“Support contact details” on page 96
.
Optical fibers,
connectors and
adapters
If an optical output is assigned to port A or B, it can be configured as either:
•
fiber patch cords with FC/APC connectors (FC/APC pig-tail)
