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 kHz、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.

Abstract

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-wavelength picosecond laser based on stimulated Raman scattering effects. Generation of visible and near-infrared band multi-wavelength picosecond laser is facilitated with methods such as focusing laser beam pump and laser pump energy optimizing and coupling, using 1 kHz repetition frequency and 532 nm wavelength 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 with an output Raman laser power of 1.76W. Results of the study can be used in the research and development of new picosecond laser sources.
