L-band ASE broadband light source

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

Product features：Spectral flatness、 Adjustable power、 Highly stable output power

Application area：Fiber optic sensing、 Medical imaging、 Fiber optic device testing
