532nm 7W High Power Diode Pumped Laser

This time it is a 532nm green DPSS laser commonly used in laboratories. Its output power can reach 7000mW.  A heat dissipation module is added to the bottom of the laser. There are 2 cooling fans at the bottom of the laser heat dissipation. There are two working modes, CW/Modulation, to choose from on the back of the power supply.


There is a protective cover on the interface where the laser head is connected to the laser power supply. When connecting, the protective cover needs to be removed first. The light outlet of the laser head has a protective cover, which must be removed before starting the machine.

The Knob on the front of the power supply is used to adjust the current, thereby controlling the laser output power. Adjust the output power to maximum. After preheating for about 1 minute, the laser can output continuously and stably.

The high power green laser beam. The following are the effects of indoor shooting during the day.



1550nm 3kHz Linewidth PM Fiber Laser Source Benchtop

Single frequency narrow linewidth fiber laser adopts rare earth doped fiber DFB laser cavity structure, output single longitudinal mode laser with wavelength of 1550nm, spectral linewidth is less than 3kHz, output spectral side mode suppression ratio exceeds 60dB.

What we demonstrate in the video is a 1550nm 200mW narrow linewidth fiber laser with a linewidth of 2.64kHz. The output optical fiber is available in SM/PM, here is the PM optical fiber. And it is fixed on the laser and is not pluggable. The optical fiber interface and length can be customized.

The laser output power can be adjusted through the button, the adjustment range is 10%~100%, and the adjustment accuracy is 1mW. The working Temperature can be fine-tuned, which can affect the laser wavelength. The adjustment accuracy is 0.01℃. The laser can also be controlled through software, and the interface on the laser is RS2023.
