摘　　要：探针光系统作为激光等离子体诊断的探针光源,它通过倍频和受激喇曼散射,将波长为1054nm、脉宽约为1ns激光转换成波长为308nm、脉宽小于60ps、能量大于1mJ的紫外光。通过预研研究和工程化改造,结果表明:探针光系统输出能量大于1mJ、脉宽小于30ps、均匀性较好、运行成功率大于90%,达到了研制标的,可满足激光等离子体诊断的要求。The optic probe is a 308 nm diagnostic light of laser plasma ,with converting a pulse of 1 ns and 1 054 nm into a pulse of output energy of over 1 mJ and 60 ps(FWHM) by stimulated Raman scatter and frequency conversion. The conclusion: The optic probe is a pulse of output energy of over 1 mJ and 30 ps(FWHM), and it runs over 90% stabilization rate, it accords with anticipated aim.
