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.
This 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 time. ‘Adjustor’ rotates clockwise to the end, which is the max working current and the maximum output power of the laser. In addition, the red ‘STOP’ button is used for emergency stop, and it is not needed under normal circumstances.
This is the free space output mode, customizable for fiber coupling.
