摘　　要：介绍了受激拉曼散射(SRS)对强激光系统的危害,主要包括强激光在空气中长距离传输时产生的受激转动拉曼散射(SRRS)与大口径KDP(磷酸二氢钾,KH_(2)PO_(4))晶体中的横向受激拉曼散射(TSRS)。研究表明,SRS不仅会损耗激光能量降低光束质量,TSRS还可能会损坏KDP晶体。针对SRS对强激光系统的危害,文章介绍了国内外关于SRS的主要抑制方案,而且重点介绍了通过控制偏振方向降低SRS增益的新思想。The hazards of stimulated Raman scattering(SRS) to intense laser systems are introduced, mainly including stimulated rotational Raman scattering(SRRS) generated by intense lasers during long-distance transmission in air and transverse stimulated Raman scattering(TSRS) in large-aperture KDP crystals. It is shown that SRS not only loses laser energy and reduces beam quality, but TSRS may also damage KDP crystals. To address the harm of SRS to the intense laser system, the main suppression schemes of SRS is introduced at home and abroad, the new idea of reducing the SRS gain by controlling the polarization direction is also focused on.
