摘　　要：针对多波长皮秒激光覆盖谱段较窄、近红外波段激光较难生成等问题,基于受激拉曼散射效应,构建了一套实验系统,采用重频1 k Hz、波长532 nm皮秒激光泵浦KGd(WO4)2晶体,运用聚焦激光束泵浦、泵浦能量优化耦合等方法,实现了可见光、近红外波段多波长皮秒激光的生成,生成七阶斯托克斯光和六阶反斯托克斯光,覆盖谱段415~800 nm,输出总功率达到1.76 W.该研究成果可应用于新型皮秒激光源的研发方面.To solve the problems of narrow coverage spectrum and difficulty of generation of near-infrared band laser,an experiment al system is developed for multi-w avelength picosecond laser based on stimulated Raman scattering effects. Generation of visible and near-infrared band multi-w avelength picosecond laser is facilitated w ith methods such as focusing laser beam pump and laser pump energy optimizing and coupling,using 1 k Hz repetition frequency and 532 nm w avelength picosecond laser source pump KGd（ WO4）2 crystal. The seventh order stokes and sixth order anti-stokes lasers generated cover the spectrum of 415 ~ 800 nm w ith an output Raman laser pow er of 1. 76 W. Results of the study can be used in the research and development of new picosecond laser sources.
