 It's a 638nm 15W semiconductor laser system .15W laser is high power, we have equipped a radiator in the laser head. The radiator at the bottom of the laser head has 3 cooling fans, which can effectively extend the continuous working time of the high-power laser. The CW/TTL/Analog on the back of the power supply has 3 switchable working modes. CW is continuous working mode. In TTL/Analog modulation mode, 1~30KHz, 0~5V signal should be connected to the 'Mod Input' BNC interface. There is a small power interface on the side of the data cable close to the laser head for the cooling fan. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode. Let's check it now. Thi is a power adjustable laser by adjusting the current. To adjust the working current, turn the 'Adjustor' knob clockwise, when the current exceeds the minimum working current, the Laser indicator turns green, and there is laser output at

This is a 26dBm polarization-maintaining EDFA. Control EDFA with buttons, and software control function can be added. It supports APC and ACC two working modes. Let's check it now. Operation method: The left and right arrow buttons are used to switch the APC and ACC working modes. In ACC mode, the up and down arrow buttons are used to adjust the working current. In APC mode, the up and down arrow buttons are used to adjust the output power. The square button in the middle is the confirmation key. After the Active key is turned ON, the EDFA starts working. Test report: Polarization-maintaining erbium-doped fiber amplifier (EDFA-PM) is a family of fiber amplifier products dedicated to polarization-maintaining fiber systems. It has the advantages of high gain, low noise, and polarization retention. It supports host computer software control. Need to provide bench-top or rack-mount package, accept parameter customization.

 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.
