![]() ![]() The major suppliers for 915/976 nm single mode pump laser diodes are companies which developed their businesses at the end of the nineties for fiber amplifiers used in the Telecom market (EDFAs: Erbium Doped Fiber Amplifiers). ![]() They are used to pump single clad active fibers (see Figure 4). These fiber coupled laser diodes are generally able to reach between 300 mW and 1.5 W of output power. This type of laser diode is generally assembled in a butterfly package with a TEC cooler integrated into the package (the trend today being towards smaller form factors). They can be separated into two major families:ġ- Single mode fiber coupled laser diodes where the light coming from a small edge-emitting laser diode is focused into a ~6 µm fiber core. Pump laser diodes that are used for fiber lasers are fiber coupled device generally based on AlGaAs III-V semiconductor technology emitting in the 800-1000 nm range (most often 915 or 976 nm – see absorption spectrum Figure 3).
