提出了一种基于高非线性光纤的光纤拉曼激光器（FRL），该光纤在宽带半导体激光二极管（LD）806 nm同步泵浦下，输出835 nm的脉冲。在600 m长的光纤中，对100 ns长的脉冲，斜率效率达到65%。我们的研究结果表明，宽条纹LD现在是足够明亮的拉曼增益，以克服相对较高的背景损耗在波长短至835 nm，我们相信这是最短的报告日期为任何二极管泵浦FRL。(C)2014年美国光学学会
We present a fiber Raman laser (FRL) based on a highly nonlinear fiber that emits pulses at 835 nm when synchronously pumped by a broadstripe semiconductor laser diode (LD) at 806 nm. The slope efficiency reaches 65% in a 600 m long fiber for a 100 ns long pulse. Our results show that broadstripe LDs are now sufficiently bright for the Raman gain to overcome the relatively high background loss at wavelengths as short as 835 nm, which we believe is the shortest reported to date for any diode-pumped FRL.
