What I’m going to talk about is 660nm and 689nm red laser.The following video demonstrates 660nm 1800mW fiber coupled laser.
The following video demonstrates the CW working mode of the 689nm 1800mW laser.
The output power of the above two lasers can be adjusted from 0 to 1800mW. They all support 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.
The optic fiber can be customized. 100μm to 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%.
