论文摘要
200 kHz，34 W，300 FS YB放大器的输出被压缩至31 Fs，效率> 88％，达到2.5 gW的峰值功率，迄今为止，这是单级体积多通电池的记录。尽管在散装材料中自我关注的关键功率高出80倍，但该设置表现出了极好的保留输入光束质量。进行了广泛的光束和脉冲表征，以表明压缩脉冲是有希望的驱动因素，可用于高谐波产生和非线性光学元件。
The output of a 200 kHz, 34 W, 300 fs Yb amplifier is compressed to 31 fs with > 88 % efficiency to reach a peak power of 2.5 GW, which to date is a record for a single-stage bulk multi-pass cell. Despite operation 80 times above the critical power for self-focusing in bulk material, the setup demonstrates excellent preservation of the input beam quality. Extensive beam and pulse characterizations are performed to show that the compressed pulses are promising drivers for high harmonic generation and nonlinear optics in gases or solids.
