 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. 

 It's a 40dBm erbium-doped fiber amplifier . The working status of this EDFA is controlled by buttons. This is a very high power fiber amplifier with 3 cooling fans inside. This EDFA is configured with single-mode fiber. The left and right buttons switch between ACC/APC two control modes. ACC automatic current control, the current setting range is 0~9600mA. APC automatic power control, the power setting range is 23~33dBm.The up and down buttons are to adjust the current/power. The middle button is the confirmation key. Let's check it now. High-power single-mode erbium-doped fiber amplifier (EYDFA-HP) is based on the principle of laser amplification of optical signals in erbium-doped fiber, using unique multi-stage optical amplification design and reliable high-power laser heat dissipation technology to achieve the wavelength range of 1540~1565nm Internal high-power laser output. It has the advantages of high power and low noise, and can be used for optical fiber communication,
