Experimental investigation on SBS phase conjugation in multi-mode quartz fiber

摘要: 采用芯径为100μm、长2m的无掺杂多模阶跃石英光纤,在1.06μm波段,研究了不同焦距下,光纤与耦合透镜间的距离以及泵浦能量对反射率和波形的影响。在不同的入射能量下,得到最大反射率为68.95%,脉宽压缩到入射光脉宽的1/3～1/2。

Abstract: Based on the pure step quartz fiber with radius of 100μm and the length of 2m,the influence of the distance between the fiber and couple lens and pump energy on reflectivity and waveform at 1.06μm is studied.The maximum reflectivity is 68.95%,and the pulse compression ration varies from on third to on second with different incident energy.
