Abstract

We present a diode-pumped Yb:YLF laser system generating 100-mJ sub-ps pulses at a 1-kHz repetition rate (100 W average power) by chirped-pulse amplification. The laser consists of a cryogenically cooled 78 K, regenerative, eight-pass booster amplifier seeded by an all-fiber front end. The output pulses are compressed to 980 fs in a single-grating Treacy compressor with a throughput of 89%. The laser will be applied to multi-cycle THz generation and pumping of high average power parametric amplifiers.

摘要

我们展示了一种二极管泵浦的 Yb:YLF 激光系统，通过啁啾脉冲放大可在 1 kHz 的重复率下产生 100 mJ 的亚皮秒脉冲（100 W 平均功率）。该激光由一个 78 K 的制冷再生式八通 booster 放大器组成，由全光纤前端种子。输出脉冲在一个单程光栅 Treacy 压缩器中压缩到 980 fs，透过率为 89%。该激光将应用于多周期太赫兹产生和高平均功率参量放大器的泵浦。
