Efficient single-frequency 910-nm fiber laser based on commercial Nd-doped silica fiber
An efficient single-frequency DBR fiber laser in the 0.9-μm wavelength region was demonstrated based on a piece of 1.9-cm-long commercial Nd-doped silica fiber. A record output power of 56.2 mW was achieved for the single-frequency laser at 910 nm with a slope efficiency of 17.8% with respect to the absorbed 808 nm pump power. This work demonstrated the feasibility of efficient quasi-three-level single-frequency laser generation in DBR short cavity configuration based on a commercially available active silica fiber with optimized parametrical design.
