The design is composed by an all-fiber laser cavity emitting in the IR range and a frequency
conversion module which converts IR laser to visible laser.
The frequency conversion module is a single pass periodically poled crystal integrated in a dust free mechanical package. This frequency conversion module is very compact and might be placed up to 3 meters ahead from the laser box.
No active cooling is required for the module. These fiber lasers represent a very reliable, robust and stable solution compare to other DPSS technologies.
