摘要
用脉宽15ns、重复频率20kHz、中心波长为1064nm的全固态Nd:YVO4激光抽运2km的G652单模石英光纤产生受激拉曼散射(SRS).得到分离的前三级斯托克斯谱和四级以上自1300nm至1700nm(光谱仪的截止频率)的超宽连续谱,并在光纤的零色散波长1310nm附近(四至六级斯托克斯频段上)观察到明显四波混频现象.
Abstract
Stimulated Raman scattering was observed when a 2km long single mode optical fiber (G652) was pumped by 1064 nm Nd:YVO4 LDPSSL light with 15ns pulse width and 20kHz repertion rate. A 3 orders-separated Stokes spectrum and a continum from 1300nm to 1700nm (the cut-off frequency of the spectrometer) above the 4th order Stokes were got. In the vicinity of 1310nm (the zero dispersion spectral band of G652 optical fiber) corresponding to the 4~6th Stokes orders, an evident four-wave mixing phenomenon apperared.
