报道了利用钛宝石激光器连续两级倍频产生准连续真空紫外相干光。在第一阶段，通过利用增强腔，获得了功率为1.1 W的399 nm的紫外光。第二阶段以KBBF晶体为非线性材料，通过单次倍频获得了199.5nm和193.5nm的准连续真空紫外相干光，其功率分别为25mW和4.7mW。
We report the generation of quasi-continuous-wave vacuum-ultraviolet (VUV) coherent light based on a Ti:sapphire laser with two successive frequency doubling stages. In the first stage, UV light at 399 nm with power of 1.1 W was obtained by exploiting an enhanced cavity. With a KBBF crystal as nonlinear material, quasi-continuous-wave VUV coherent light with power of about 25 mW at 199.5 nm and 4.7 mW at 193.5 nm were achieved through a single-pass SHG configuration, respectively, in the second stage.
