Stimulated Raman Scattering and Stimulated Four photon Mixing in Er doped Silica Fiber

报道了掺铒光纤受激拉曼散射（ＳＲＳ）和受激四光子混频（ＳＦＰＭ）的实验研究。所用光纤长为１０ｍ，泵浦源为ＮｄＹＡＰ倍频５３９．７ｎｍ脉冲激光，脉冲能量为０．１Ｊ，脉宽为５０ｎｓ，获得了从５５２．１～６２２．８ｎｍ的６级受激拉曼散射谱和受激四光子混频的Ｓｔｏｋｅｓ（５４２．９ｎｍ）及反Ｓｔｏｋｅｓ（５３７ｎｍ）谱线。

This paper describes the experimental investigation of stimulated Raman scattering and stimulated four photon mixing obtained from an Er doped silica fiber. Six orders of stimulated Stokes scattering in the range of 552.1～622.8 nm and the Stokes (λ=542.9 nm) and anti Stokes (λ= 537 nm) of stimulated four photon mixing have been obtained from a 10 m Er doped single mode silica fiber, which was pumped by a frequency doubled Q switched Nd∶YAP laser (λ=539. 7 nm) with a pulse duration of 50 ns. Its output energy is 0.1 J.
