中文摘要:多波长皮秒激光在非线性光学、光通信等领域有广泛应用前景,因此倍受关注。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1kHz、波长532nm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415nm~800nm,输出总功率达到1.76W。该研究成果可应用于新型皮秒激光源的研发方面。

Research on Multi-Wavelength Picosecond Laser in visible and near-infrared band
Abstract:Multi-wavelength picosecond laser has widely application foreground in nonlinear optics and optical communications etc domains,so it is noticed at all times. In allusion to narrower coverage band and near-infrared band generation difficulty problem of Multi-wavelength picosecond laser, based on stimulated raman scattering effects,a experiment system of multi-wavelength picosecond Laser has been constructed. 532nm Wavelength and 1kHz repetition frequency picosecond laser is employed as pump sources, and KGd(WO4)2 crystals as Raman crystals. Multi-wavelength picosecond laser in visible and near-infrared band is generated by using methods of focusing laser and pump laser energy optimizing coupled with crystals,including seven order stokes and six order anti-stokes lasers,and covering 415nm~800nm band, output Raman laser power is 1.76W. This result can be used for researching new type Picosecond Laser.
