我们报道了一个超过150w的光谱清洁的连续波拉曼光纤激光器，在1120nm，光效率为85%。采用与30 m标准单模石英光纤相似的光纤作为拉曼增益光纤，避免了二次斯托克斯发射。设计了一种带有普通光纤布拉格光栅的频谱不对称谐振器（镜面反射带宽意义上的谐振器），即使当后部光纤布拉格光栅的有效反射率低至81.5%时，也能最大限度地减少激光在不需要的方向上的功率损失。(C) 2009年美国光学学会
We report a more than 150 W spectrally-clean continuous wave Raman fiber laser at 1120 nm with an optical efficiency of 85%. A similar to 30 m standard single mode silica fiber is used as Raman gain fiber to avoid second Stokes emission. A spectrally asymmetric resonator ( in the sense of mirror reflection bandwidth) with usual fiber Bragg gratings is designed to minimize the laser power lost into the unwanted direction, even when the effective reflectivity of the rear fiber Bragg grating becomes as low as 81.5%.
