| 摘 要： | 利用 Nd:YAG四倍频激光抽运氘气 (D2 )的受激拉曼效应 ,获得一阶斯托克斯 (Stokes)波长2 89nm。通过改变拉曼介质 D2 气压与抽运光能量 ,获得了一阶斯托克斯输出的较佳条件。该波长与 Xe Cl准分子激光波长 30 8nm采用差分吸收方法 ,建立了用于对流层臭氧探测的激光雷达 ,并初步获得了对流层大气臭氧的垂直分布及其时间变化特征。

| Abstract: | The first Stokes line 289 nm is generated by deuterium (D2) stimulated Raman scattering pumped by fourth harmonic Nd:YAG laser. By changing D2 pressure and pump energy, the conditions for 289 nm output were optimuzed. Based on differential absorption principle, a laser radar has been developed for monitoring tropospheric ozone using Stokes output at 289 nm and XeCl laser output at 308 nm. The distribution profiles of tropospheric ozone and their temporal variation are reported in this paper. |
