All-fiber widely tunable Raman fiber laser with controlled output spectrum.
A simple all-fiber widely tunable phosphosilicate Raman fiber laser (RFL) of high efficiency has been developed. The laser has more than 50 nm tuning range, and generates up to 3.2 W of output power with 72% maximum slope efficiency. The output power is almost constant in the range 1258-1303 nm. The width and the spectral power density of the RFL output spectrum can be controlled by the detuning of its cavity fiber Bragg gratings (FBGs) thus being optimized for efficient frequency doubling.
