报道了KBe2BO3F2(KBBF)晶体倍频(SHG)脉冲重复频率(PRR)可调的深紫外皮秒(PS)辐射的实验研究和理论分析。泵浦光源为脉冲重复频率为200 kHz-1 MHz的ps Nd：YVO4激光器，其输出波长为355 nm。在不同的重复频率下测量了177.3 nm输出功率与抽运功率的关系，在重复频率为200kHz时，获得了最大的177.3 nm平均输出功率695μW。测量数据与PS KBBF倍频理论模拟结果吻合较好。模拟结果表明，在177.3 nm处产生的激光脉冲宽度为5.88ps，光谱带宽为7.84 pm。
We reported on an experimental investigation and theoretical analysis of pulse repetition rate (PRR) adjustable deep ultraviolet (DUV) picosecond (ps) radiation by second harmonic generation (SHG) in KBe2BO3F2 (KBBF) crystal. Third harmonic radiation at 355 nm of a ps Nd:YVO4 laser output with PRR of 200 kHz–1 MHz was employed as the pump source. The dependence of the 177.3 nm output power on the 355 nm pump power was measured at different PRRs, and the maximum 177.3 nm average output power of 695 μW was obtained at the PRR of 200 kHz. The measured data agreed well with the results of the ps KBBF SHG theoretical simulations. Using simulations, the pulse width and the spectral bandwidth of the generated radiation at 177.3 nm were estimated to be 5.88 ps and 7.84 pm, respectively.
