报道了一台100 W连续波包层抽运光纤拉曼激光器，工作波长为1120 nm。光纤拉曼激光器由一个4% - 100%线性腔中的85 m长的掺锗双包层光纤组成，由一个1064 nm的多模掺镱光纤激光源端面泵浦。相对于发射的泵浦功率，拉曼激光器具有71%的斜率效率。在80 W的输出功率下，测得激光输出M2为~ 1.6。
We report a 100 W continuous-wave cladding-pumped fiber Raman laser operating at 1120 nm. The fiber Raman laser consists of an 85 m long germanium-doped double-clad fiber in a 4% - 100% linear cavity, which is end-pumped by a multimode ytterbium-doped fiber laser source at 1064 nm. The Raman laser has a slope efficiency of 71% with respect to launched pump power. The laser output M2 is measured to be ~ 1.6 at 80 W of output power.
