The fiber ASE broadband light source is an incoherent light source, which is the spontaneous radiation generated by the semiconductor laser pumping erbium-doped silica fiber, and the spectral flattening technology is introduced to achieve a broadband flat spectrum. The wavelength of the light source covers the C+L band, and the spectral flatness is better than 3dB. It is output through single-mode fiber or polarization-maintaining fiber, which is suitable for applications such as fiber sensing.

This is a  C+L Band 100mW ASE broadband light source. The wavelength range is 1528nm~1603nm. The power can be adjusted by the button, and the adjustment accuracy is 1mW. The adjustment range is 10%~100%. We need to use infrared photosensitive film to observe the light spot of the laser in this band.

The test data report of this ASE broadband light source.

How to use the desktop ASE broadband light source:
Turn on the power switch on the back of the machine. After power on, the LCD displays the current power and wavelength range.
Press the middle square button to start setting the power. The left and right buttons are used to select the digit to be adjusted. The up and down buttons are used to adjust the value. Finally, press the middle square button to confirm the setting. The key is turned to ON, and the Active indicator lights up, indicating that the laser starts outputting.
