Amplified Spontaneous Emission
ASE (Amplified Spontaneous Emission) light sources are designed specifically for production and laboratory experiments. The main part of the light source is a gain medium erbium-doped fiber and a high-performance pump laser. The unique ATC and APC circuits ensure stable output power by controlling the output of the pump laser. By adjusting the APC, the output power can be adjusted within a certain range. Simple and intelligent operation and remote control.
