What we are going to demonstrate in today’s video is a 772nm 1W fiber coupled laser. The output power of the laser is adjustable from 0 to 1000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/Analog modulation mode, an external modulation signal needs to be connected.

The optical fiber is pluggable and customizable. The fiber core diameter,fiber length and interface can be customized according to customer needs. 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%.

The 772nm laser is a near-infrared laser, and the light spot is dim.
