 This is 940nm 20W IR Laser Source . The laser head has a heat dissipation base, which can effectively extend the continuous working time of the laser. The radiator has two cooling fans. The back of the laser head and the power supply, the 3 working modes of the laser, CW/TTL/Analog are set from the back of the power supply. The 940nm laser is an infrared laser invisible to the naked eye, and a faint red light can be seen in the camera. But the energy is very strong. We shine a laser on the cardboard and it catches fire immediately. 20W is very high power laser , you need to wear IR laser protective glasses when operating, and do not use the laser to irradiate human eyes at any time. In addition, the red STOP button is used for emergency stop, and it is not needed under normal circumstances.

 It's 532nm fiber coupled laser system. It's a output power tunable laser, 0~20W laser power can be adjusted by button. This laser has three working modes: CW, TTL modulation, Analog modulation. It coupled a SMA905 fiber, the coupling efficiency is about 80% at 400μm fiber. After turning on the laser, it need a few minutes for the laser to work stably. Let's check it now.
