多程池中milliJoule能量Ti：Sa飞秒脉冲的单级少周期非线性压缩
Single-stage few-cycle nonlinear compression of milliJoule energy Ti:Sa femtosecond pulses in a multipass cell
摘要：
本文报道了在充氩的多程池中，Ti：Sa啁啾脉冲放大系统产生的兆焦耳能量脉冲的非线性时间压缩。脉冲从30 fs压缩到5.3 fs，对应于两个光学周期。压缩后的光束具有良好的空间质量和均匀性。这些结果为Ti：Sa脉冲的鲁棒和能量可扩展压缩到几个周期的范围铺平了道路。
英文摘要：
We report on the nonlinear temporal compression of mJ energy pulses from a Ti:Sa chirped pulse amplifier system in a multipass cell filled with argon. The pulses are compressed from 30 fs down to 5.3 fs, corresponding to two optical cycles. The post-compressed beam exhibits excellent spatial quality and homogeneity. These results pave the way to robust and energy-scalable compression of Ti:Sa pulses down to the few-cycle regime.
