435nm 18W Blue Semiconductor Laser Fiber Output

Today we are showing the 435nm fiber coupled laser. The power is 18W, and it is adjustable. The Adjustor button on the power supply is used to adjust the working current, and the laser output power can be adjusted by adjusting the current. The laser supports CW continuous working and Modulation working mode, which can be adjusted by the slider button on the back of the laser power supply. Next we demonstrate the CW working mode of this laser. Let’s check it now.

808nm 100mW Semiconductor Laser Coupled PM Optical Fiber

808nm fiber-coupled laser uses PM fiber coupling, which has the advantages of high coupling efficiency and good output laser beam quality. The TEC temperature control system is used to ensure that the laser is more stable and has better performance. Compact structure, strong and reliable, suitable for various industrial and scientific research applications.

This is 808nm 100mW infrared lab laser system coupled PM fiber. The working voltage is AC 90~240V and supports wide range voltage. Its laser power can be adjusted from 0~100mW, and it supports two working modes of CW/Modulation.
808nm is infrared laser, invisible laser, here use infrared sensitive film to observe the spot.

37dBm Yb-doped SM Fiber Amplifier Benchtop

It’s a high power Ytterbium-doped optical amplifier, its output power is 37dBm. And high power YDFA built-in 3 cooling fans. The software control function can be customized, and the default is button control. The current working mode, current and output power are displayed on the front display.


It supports APC and ACC two working modes, and the two modes can be switched. In ACC mode, the working current can be adjusted. In APC mode, the output power can be adjusted.
