We report on an 880 nm quasi-continuously pumped Nd:YVO4 grazing-incidence "bounce" amplifier, operating at a 300 Hz repetition rate. More than 70 dB small signal gain is achieved with a single crystal. Combined with fast programmable modulators, high-contrast and near-diffraction-limited pulse sequences at the 100 μJ level are produced and can be tailored in terms of pulse duration, amplitude, and a temporal spacing well into the microsecond range. This system could significantly improve extreme-UV comb generation based on parametric amplification and harmonic upconversion of two near-IR comb laser pulses.
我们报告了一种 880nm 准连续抽运 Nd:YVO4 掠入射“反弹”放大器，其工作重复率为 300Hz。单晶体实现了超过 70dB 的小信号增益。结合快速可编程调制器，可产生高达 100μJ 水平的高对比度和近衍射极限脉冲序列，并可根据脉冲持续时间、幅度和微秒级的时间间隔进行调整。该系统可以显著改善基于参量放大和两个近红外梳状激光脉冲的谐波上转换的极紫外梳状产生。
