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 probe light system, as a probe light source for laser plasma diagnosis, converts the laser light with the wavelength of 1054 nm and the pulse width of about 1 ns into a wavelength of 308 nm, a pulse width of less than 60 ps and an energy of more than 1 mJ by double frequency and stimulated Raman scattering UV light. The results show that the output power of the probe system is more than 1mJ, the pulse width is less than 30ps, the uniformity is good and the success rate of operation is more than 90%, which has reached the standard of development and can meet the needs of laser plasma diagnosis Claim.
