摘要
采用单频高功率Nd:YVO4激光的倍频光(532 nm)作为抽运源,激发长度为250 m和920 m的单模石英光纤,开展了石英光纤在可见光谱范围内的受激拉曼散射实验研究,获得了宽带宽的、第1级到第4级受激拉曼散射Stokes光谱,拉曼频移峰值分别为450 cm-1,1064 cm-1,1610 cm-1和2168 cm-1.
Abstract
The frequency doubled output of a single frequency Nd∶YVO 4 laser centered at λ0=532 nm was used as input pump to excite single mode fused silica fibers with length of 250 m and 920 m, respectively. The study on broadband SRS Stokes spectrum within range of visible spectrum in fused silica fibers was made. The first order to the fourth order SRS Stokes spectra were obtained, and frequency shift peak was at 450 cm-1, 1064 cm-1, 1610 cm-1 and 2168 cm-1, respectively.
