摘要

A tunable continuous wave single-longitudinal-mode fiber laser is proposed anddeveloped. A saturable absorber, as well as, an all-fiber Fabry-Perot filter was used in thelaser cavity to reduce mode-hopping. The laser was tunable from 1 565nm to 1 575nm and could produce an output power of 300m W while still maintaining single-mode operation with no mode-hoping. The linewidth of the laser was ?9 MHz. The stability of the laser based on the length of the saturable absorber and the modal structure has been explored. We developed two Brillouin fiber lasers using this laser as a pump source. A highly nonlinear photonic crystal fiber and a chalcogenide fiber were used as the nonlinearmedium. The Brillouin fiber laser based on PCF could produce either single wavelengthor multiwavelength laser outputs. Further, we investigated the coupling mechanism forthe pump light into the chalcogenide glass fiber. In all cases the lasers were operated atroom temperature.
