摘要
本文报道了光导中单束激光无聚焦多次反射激励喇曼介质H_2,使得同步入射的H_2的斯托克斯种子光得到耦合放大,放大系数大于2。
In this paper, we report the coupling amplification of the Stokes seed beam in Raman medium H2, which is excited by a single laser reflected many times in a light guide without focusing. The amplifying coefficient over 2 is observed and the quality of the amplified beam is the same as or more better than the seed beam.
