 This is 445nm 24W high power semiconductor laser . The power supply has LED display, which can display the current working current. The 'Adjustor' knob is used to adjust the current to control the output power. On the back of the laser power supply, there are 3 working modes to choose from: CW, TTL and Analog. The laser head can be customized to add heat sink, fiber coupling can also be custom added. Demonstration of laser operation: Connect the AC power cord. Slide the working mode to CW, continuous light mode. Connect the laser head and laser power supply. Insert the key. Turn on the power switch, the red button goes to ON. Then turn on the laser control key, the key turns ON. Rotate the knob Adjustor to adjust the laser output power to a suitable size. Important reminder: It is strictly forbidden to irradiate the human body with laser light, especially the eyes. Laser protective glasses must be worn during operation. This 24W high-power laser , the reflected light may als...

 It's a 543nm 10mW DPSS laser system . The back of the laser head is equipped with a cooling fan. There are 3 working modes available on the back of the laser power supply, CW, TTL and Analog. The red button is pressed to be ON, and the power is turned on. When the safety key is turned ON, laser output starts at this time. Rotate the'Adjustor' button and turn it clockwise to increase the current, thereby increasing the laser output power. Let's check it now. The center wavelength is 542.8nm. And its spot is perfectly round, it is TEM00 mode.
