摘　　要：单模光纤SRS的实验用的是Nd:YAG调Q倍频激光作泵浦源,用快速雪崩二极管探测光脉冲信息,用存储示波器记录波形,光路如图1。图中1是JGM-1型色心调QNd:YAG激光器,倍频后(0.53μm)脉宽为20ns,输出能量为125μJ～100mJ。2是滤去1.06μm剩余光的滤光片,3是分束片,4是LPE-IA激光功率/能量计,以监视输入能量,5、7是耦合透镜,6是光纤,8是单色仪,9是Ge-Stimulated Raman Scattering (SRS) in germanium-doped silicate monomode fiber are discussed in the visible light range. The pump and three orders of Stokes pulses depleted by their next Stokes pulse have been obtained. Each stokes pulse is Shorter than that of the previous order.
