Is is a 689nm red laser system. The output power of the laser is adjustable from 0 to 1800mW. It supports 3 working modes, CW/TTL/Analog. In TTL/Analog modulation mode, an external modulation signal needs to be connected. The following video demonstrates the CW working mode of the laser.

This laser is equipped with a pluggable optical fiber. CivilLaser’s solid-state lasers can be customized for fiber-coupled output. 100μm~1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80~90%.

The power adjustment method of Lab adjustable power supply:
Turn the ‘Adjustor’ knob on the power supply clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the ‘Adjustor’ is rotated clockwise to the end, it is the max working current and the max output power of the laser.
In addition, the red STOP button is used for emergency stop, and it is not used under normal circumstances.
