1342nm激光泵浦光子晶体光纤受激喇曼散射的实验研究(英文)

Investigation on Stimulated Raman Scattering in Photonic Crystal Fiber Pumped by 1342 nm Laser

利用调QNd∶GdVO4激光器为泵浦源,对100m非线性光子晶体光纤中受激拉曼散射谱的形成过程进行了实验研究.随着泵浦功率的增加,在中心～1575nm处得到一个宽带光谱,并观察到光谱内部出现能量红移现象,使得光谱能量从1546nm处转移到1615nm.

The stimulated Raman scattering with 100 m nonlinear PCF using a Q - switched 1 342 nm Nd ： GdVO4 laser as the pump source was studied. The first order Stokes light evolving versus incident pump power was presented. And a broad spectrum with a peak center at -1 575 nm was appeared when the pump power increased. The spectrum process observed in the experiment was discussed. An energy red shift was also found from 1 546 nm to 1 615 nm.
