摘要

A watt-level tunable 1.5 mu m narrow linewidth fiber ring laser using a temperature tuning pi-phase-shifted fiber Bragg grating (pi-PSFBG) is demonstrated here, to the best of our knowledge, for the first time. The p-PSFBG is employed as both a narrow band filter and a wavelength tuning component, and its central wavelength is thermally tuned by a thermo-electric cooler. The maximum laser power is about 1.1 W with a linewidth of similar to 318 MHz (similar to 2.57 pm) and a power fluctuation of less than 3%. The wavelength tuning range of the laser is about 1.29 nm with a sensitivity of similar to 14.33 pm/degrees C, and the wavelength fluctuation is about 0.2 pm. This work provides important reference for tunable fiber lasers with both high power and narrow linewidth. (C) 2017 Optical Society of America
