摘要
我们将主激光分出一部分做为探测束,探测束经过KDP晶体倍频,然后用DMSO液体后向喇曼散射移频到630nm,最后经BBO晶体倍频,最终获得的探测束波长为315nm,脉冲宽度为10～20ps,脉冲能量大于0.2mJ。
A portion of the main beam was split off to form the probe beam. This beam was frequency doubled with a KDP crystal, frequency shifted to 630nm by backward Raman scattering in DMSO, and finally frequency doubled in a BBO crystal. The probe pulse wavelength was 3l5nm, pulse width 10-20ps, and pulse energy greater than 0.2mJ.
