High-efficiency single-frequency Brillouin fiber laser with a tunable coupling coefficient


We theoretically analyze a high-efficiency single-frequency Brillouin all-fiber ring laser at 1.5 mm wavelength, taking pump depletion into account. The output pump and Stokes intensities are calculated as functions of the cavity coupling coefficient and of the input pump intensity. Lasing threshold and pump-to-Stokes conversion efficiency are predicted… (More)
