摘要

摘要报道了一种单光纤布拉格光栅(FBG)连续掺铥光纤激光器。无源光纤端面的菲涅耳效应和高反射率光纤光栅建立了谐振腔。激光的峰值波长为1942.25 nm，谱线宽度为194 pm。最大输出功率为37.5 W，斜率效率为63.7%，光束质量因子为m2 ~ 1.51。据我们所知，这是由793 nm激光二极管泵浦的TDF激光器的最高斜率效率。

High-efficiency continuous-wave Tm-doped fiber laser with a single fiber Bragg grating at 1942 nm

Abstract We report a continuous-wave Tm-doped fiber (TDF) laser with a single fiber Bragg grating (FBG). The Fresnel effect presenting in the passive fiber end-face and high-reflectivity FBG established the resonator. The peak wavelength of the laser was 1942.25 nm with a spectral linewidth of 194 pm. The maximum output power was 37.5 W, corresponding to a slope efficiency of 63.7% with a beam quality factor of M 2 ∼ 1.51. To the best of our knowledge, this is the highest slope efficiency of a TDF laser pumped by 793 nm laser diode.
