标题： High Power, Continuous-wave Supercontinuum Generation in Highly Nonlinear Fibers Pumped with High Order, Cascaded Raman Fiber Amplifiers

摘要： 一种在全常规石英光纤架构中高效生成高功率、均衡连续波超连续谱光源的新方法得到展示。 使用一种新型高功率L波段激光器，在非正常色散区域对高非线性光纤（HNLF）进行泵浦。 L波段激光器包含一个6阶级联拉曼放大器，该放大器由高功率掺镱光纤激光器泵浦，并放大一个低功率、可调谐的L波段种子源。 产生的超连续谱功率达到35W，效率约为40%。 测得的超连续谱光谱具有很高的平坦度，在400 nm带宽（1.3 - 1.7微米，受限于光谱分析仪范围）内优于5 dB，并且该区域的功率光谱密度超过50 mW/nm。 估计超连续谱的范围可达2微米。 显示英文摘要

摘要： A novel method for efficient generation of high power, equalized continuous-wave supercontinuum source in an all conventional silica fiber architecture is demonstrated. Highly nonlinear fiber (HNLF) is pumped in its anomalous dispersion region using a novel, high power, L-band laser. The L-band laser encompasses a 6th order cascaded Raman amplifier which is pumped with a high power Ytterbium doped fiber laser and amplifies a low-power, tunable L-band seed source. The supercontinuum generated 35W of power with ~40% efficiency. The Supercontinuum spectrum was measured to have a high degree of flatness of better than 5 dB over 400 nm of bandwidth (1.3 - 1.7 micron, limited by spectrum analyzer range) and a power spectral density in this region of >50 mW/nm. The extent of the SC spectrum is estimated to be upto 2 micron
