| 摘 要： | ps激光探针作为激光等离子体诊断的探针光源，它是通过两次倍频和两次受激喇曼散射，将波长为1 054nm、脉宽约为1ns激光转换成波长为308nm、脉宽小于30ps的紫外光。研究结果表明：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%，满足了激光等离子体诊断的要求。

| Abstract: | The ps laser probe is a 308nm diagnostic light source for laser plasma diagnosis. It coverts a pulse of lns 1 054nm into a pulse of 263nm by double times frequency conversion, then it compresses 1ns to 30ps(FWHM) and the wavelength is shifted to 308nm by stimulated Raman scattering, at last the output laser is a pulse of output energy over 1mJ and 30ps.The experimental result is that the ps laser probe is output pulse of over 1mJ energy and 30ps(FWHM), and it runs over 90% stable rate, it accords with anticipated aim. |
