利用KBe(2)BO(3)F(2)棱镜耦合器件，通过产生倍频钛宝石激光器的二次谐波，实现了170至232.5 nm宽范围内的高平均功率输出。 175至232.5 nm紫外光下的输出功率超过2 mW，其中202.5 nm处的最高功率为119.8 mW。此外，193.5至200 nm的深紫外光也获得了100 mW以上的可调输出功率。
Using a KBe(2)BO(3)F(2) prism-coupled device, we have realized the high-average-power output in the wide range from 170 to 232.5 nm by second-harmonic generation of a frequency-doubled Ti:sapphire laser. The output power in the UV from 175 to 232.5 nm exceeds 2 mW, the highest power being 119.8 mW at 202.5 nm. Moreover, tunable output powers above 100 mW have also been obtained for deep-UV light from 193.5 to 200 nm.
