20W 880nm Fiber Coupled Laser: This is 880nm 20W high power infrared laser. A fiber coupling interface is added to the laser output port, which can be inserted into a fiber. A cooling device is added at the bottom of the laser module, which is composed of aluminum sheet and cooling fans. The laser supports CW continuous work and modulation work mode, which can be adjusted by the slider button on the back of the laser power supply. The 880nm laser is a near-infrared laser, basically invisible, only a faint red dot can be seen on the light shield. 405nm 5W High Power Fiber Laser Source It's a 405nm 5W Fiber coupled laser system. The radiator is composed of aluminum sheets and 2 fans. We use 600μm fiber for this laser system. Let's check it now. Turn on the laser and adjust the power to the maximum value. The laser beam is emitted from the optical fiber. 520nm 15W High Power Fiber Coupled Laser System It's a 520nm 15W fiber coupled laser system. There is a radiator at the bottom of the laser head. The radiator is composed of an aluminum sheet and a cooling fan. The'Adjustor' knob on the power supply is used to adjust the size of the current to control the laser output power. The'CW|TTL|Analog' on the back of the laser power supply is the selection button for 3 working modes. Powerful Red Fiber Laser System -- 638nm 30W Laser It's a 638nm 30W high power fiber coupled laser system. There are CW/TTL/Analog 3 working modes available on the back of the power supply. When TTL/Analog is selected, external signal access is required. A radiator is added to the bottom of the laser head to extend the continuous working time of the laser. The heat sink under the laser head integrates 3 cooling fans. We add a collimator on the fiber output port, the focal length is adjustable. Turn on the laser and adjust the current of the power supply to adjust the output power of the laser. The strong red laser beam from collimator port.
