Abstract

We report on the generation of 1.0 PW, 30 fs laser pulses at a 0.1 Hz repetition rate from a chirped-pulse amplification Ti:sapphire laser system. The energy of the laser pulses is amplified up to 47 J in a final three-pass booster amplifier having 96 J pump energy. To the best of our knowledge, this is the first petawatt Ti:sapphire laser system at a 0.1 Hz repetition rate. The shot-to-shot energy fluctuation of the laser pulses is as low as 0.53% in rms value, and the laser pulses have homogeneous flattop spatial beam profiles.

摘要

我们报告了一种啁啾脉冲放大钛宝石激光系统，其能够产生 1.0 PW、30 fs、0.1 Hz 重复率的激光脉冲。激光脉冲的能量在最后一个具有 96 J 泵浦能量的三程增强型放大器中被放大到 47 J。据我们所知，这是第一个 0.1 Hz 重复率的皮瓦级钛宝石激光系统。激光脉冲的单次能量波动低至 RMS 值的 0.53%，且激光脉冲具有均匀的平顶空间光束轮廓。
