摘要

本文报道了利用受激拉曼散射在h2填充空心光子晶体光纤(PCF)中实现的首个百瓦连续波光纤气体激光器。泵浦源为国产窄线宽光纤振荡器，线宽为3db, 0.15 nm，最大输出功率为380w。为了高效、稳定地将几百瓦的泵浦功率耦合到空芯中并对气体进行密封，在输入端制作了空心光纤端盖。在长5 m、填充36 bar H2的空心PCF中，在1153 nm处获得了110 W的最大功率，第一Stokes功率的转换效率约为48.9%。这项工作为高功率光纤气体拉曼激光器铺平了道路。

A 110 W fiber gas Raman laser at 1153 nm

Abstract We report here the first hundred-watt continuous wave fiber gas laser in H2-filled hollow-core photonic crystal fiber (PCF) by stimulated Raman scattering. The pump source is a homemade narrow-linewidth fiber oscillator with a 3 dB linewidth of 0.15 nm at the maximum output power of 380 W. To efficiently and stably couple several-hundred-watt pump power into the hollow core and seal the gas, a hollow-core fiber end-cap is fabricated and used at the input end. A maximum power of 110 W at 1153 nm is obtained in a 5 m long hollow-core PCF filled with 36 bar H2, and the conversion efficiency of the first Stokes power is around 48.9%. This work paves the way for high-power fiber gas Raman lasers.
