| Abstract: | High power 980-nm strained QW semiconductor lasers connected to the input ports of a 4×4-fused fiber star coupler are simultaneously wavelength-locked through reflection from a single narrow-band fiber grating connected to one output port. This configuration enables simple pump wavelength control, inhibits deleterious pump-laser interactions, and improves amplifier reliability through pump redundancy |
