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.
The laser from optical fiber output port.
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.
