摘要
介绍了一种用氮分子激光泵浦的带有一级放大的染料激光器，再由ＢＢＯ晶体倍频，获得了波长为 ２１７．５ ｎｍ到 ３０９．０ ｎｍ的可调谐紫外相于光，并测得波长分别为４７０．０， ５０７．４， ５４６．０ ｎｍ，三处的倍频光最大信频转换效率为 ５％， ９％． １２％。分析表明，这些结果与理论相符合．
A dye laser containing an order amplifier which is pumped by a N2 laser is given in this paper. Moreover, the properties of BBOs doubling frequency for the dye laser are discussed and tunable SHG output from 217.5 um is obtained. The values of maximum conversion efficiency are 5 % (at 235.0nm), 9% (at 253 nm) and 12% (at 273.0 nm). The results of experiments correspond are in good consistency with theory.
