本文利用ＹＡＧ激光泵浦光导纤维产生受激喇曼散射，并利用所摄取的受激喇曼光谱图定出斯托克斯线波长，计算样品的喇曼频移，对实验中所观察到的现象进行分析讨论。
In this paper, the stimulated Raman scattering was produced by pumping optical fiber with YAG laser and the Stokes wavelength was determined by using the stimulated Raman spectra. The Raman shift of the sample was calculated. Phenomenon analysis and discussion.
