C-band 20mW ASE Light Source Micro Module With SM Fiber

The light source outputs a flat spectrum covering the C-band and has moderate output power. At the same time, due to the unique miniaturized design and miniature package, it is the smallest ASE broadband light source at present, which is very suitable for applications in narrow space conditions. Let’s check it now.

This is a C-Band 20mW Micro ASE light Source, 10mW~50mW output power can be customized. After turning on the laser, the green indicator light will light up. And the ASE starts working, with invisible light output in the 1528~1563nm band.

405nm SM Fiber Laser Controlled by Button Operational Demo

This is a video about a desktop laser with button control of the laser output. we demonstrate with a 405nm 20mW SM fiber laser. It is controlled by buttons by default, and it can also be controlled by software. The laser is equipped with single-mode fiber output, and polarization-maintaining fiber output can also be customized. It has LCD display, real-time display of current power. The power is adjustable, and the adjustment accuracy is 0.1mW. Let’s check it now.

Adjust the laser output power:
Press the middle square button to enter setup mode.
The left and right arrow buttons are used to select the digital position to be adjusted.
The up and down arrow buttons are used to adjust the size of the numbers.
Finally press the middle square button to save and exit the settings.
When the key is turned ON, the Active indicator lights up, indicating that there is laser output.


This laser adopts semiconductor laser chip, and the professionally designed drive and temperature control circuit temperature control ensures the safe operation of the laser, stable output power and spectrum, and excellent spot quality (TEM00 mode).
