title: Single-frequency Brillouin lasing using single-mode As(2)Se(3) chalcogenide fiber.
abstract: Brillouin lasing in a single-longitudinal mode at 1.55 mum is demonstrated using As2Se3 single-mode fiber for the first time. The As(2)Se(3) fiber provides sufficient Brillouin gain for the Stokes wave to initiate single frequency oscillation in a 2-m long fiber Fabry-Perot cavity with a nonresonant pump power of 56 mW. For a pump power of 78 mw, 12 mW of Stokes power was obtained, which corresponded a conversion efficiency of 15%.
