【摘要】 本文详细地研究了双折射光纤的受激喇曼散射.我们已经观测到9级斯托克斯受激喇曼谱.讨论并测试了阈值和喇曼频移与泵浦光偏振方向间的关系,测试了当泵浦光偏振方向与光纤椭圆核的长轴或短轴平行时的传输损耗.并根据测得的阈值在理论上计算了各级斯托克斯线的喇曼增益系数.更多还原

【Abstract】 In the paper, Stimulated Raman scattering (SRS) of birefringence fiber is in detail discussed. We have alrady observed 9-th order Stokes line of SRS. The dependence of threshold and Raman shift on polarization of pumping light are duscussed. The transmission loss of pumping light polarization in the disection of major or minor axis of fiber core are measured. SRS gain coefficient of birefringence fiber is theoretically calculated by measured threshold.更多还原
