光波控制的相对论性等离子体镜

Lightwave-controlled relativistic plasma mirrors

Marie Ouillé, Jaismeen Kaur, Zhao Cheng, Stefan Haessler, Rodrigo Lopez-Martens

AI总结:

本文利用kHz重复频率的近单周期相对论光波驱动等离子体镜,通过控制强光瞬态波形实现高次谐波与电子发射的阿秒尺度控制,成功产生孤立阿秒脉冲,并观察到波形相关的相对论性电子束发射。

摘要:

我们报告了在kHz重复频率下,由相对论强度近单周期光波驱动的等离子体镜的高次谐波与电子发射的阿秒尺度控制。通过控制强光瞬态的波形,我们在等离子体镜表面可重复地形成亚周期时间强度门,从而观察到极紫外光谱连续谱,这是产生孤立阿秒脉冲的特征。我们还观察到与波形相关的相对论性电子束的发射,为实现相对论性等离子体镜动力学的完全光波控制铺平了道路。

英文摘要:

We report on attosecond-scale control of high-harmonic and electron emission from plasma mirrors driven by relativistic-intensity near-single-cycle lightwaves at kHz repetition rate. By controlling the waveform of the intense light transient, we reproducibly form a sub-cycle temporal intensity gate at the plasma mirror surface, leading to the observation of extreme ultraviolet spectral continua, characteristic of isolated attosecond pulse generation. We also observe the correlated emission of a waveform-dependent relativistic electron beam, paving the way towards fully lightwave-controlled dynamics of relativistic plasma mirrors.
