532 nm激光抽运CO_2气体的多光谱拉曼激光
|
摘要
基于受激拉曼散射(SRS),研究了一种获得多光谱激光的方法。以Nd\:YAG的二倍频532 nm激光为抽运光,以高压CO_2作为拉曼活性介质,最多可同时输出位于390～755 nm的10种波长。通过优化CO_2压力,得到一级斯托克斯光(S1,574 nm)、二级斯托克斯光(S2,624 nm)和三级斯托克斯光(S3,683 nm)的最大光子转换效率分别为36.6%、19.6%和11.2%。
Based on stimulated Raman scattering(SRS), we study a method for obtaining multispectral laser. The frequency doubled Nd\:YAG laser at 532 nm is used as the pumping light, and the high pressure CO_2 is used as Raman active medium, and ten different Stokes lasers between 390 nm and 755 nm are generated simultaneously. By optimizing CO_2 pressure, the maximum photon conversion efficiencies for first-order Stokes(S1, 574 nm), second-order Stokes(S2, 624 nm) and third-order Stokes(S3, 683 nm) reach 36.6%, 19.6% and 11.2%, respectively.
