标题： Anticorrelated emission of high-harmonics and fast electron beams from plasma mirrors

摘要： 我们首次报告了在由高强度超短激光脉冲驱动的具有尖锐真空界面$-$等离子体镜$-$的高密度等离子体中，高阶谐波和高能电子束的反相关发射。 我们通过测量等离子体镜发射的谐波和电子束的空间和光谱特性，强调了等离子体表面纳米结构在相互作用中的关键作用。 我们表明，等离子体镜的纳米尺度行为可以通过调节电子密度梯度的尺度长度来控制，该尺度长度通过空间域干涉测量法进行原位测量。 显示英文摘要

摘要： We report for the first time on the anticorrelated emission of high-order harmonics and energetic electron beams from a solid-density plasma with a sharp vacuum interface$-$plasma mirror$-$driven by an intense ultrashort laser pulse. We highlight the key role played by the nanoscale structure of the plasma surface during the interaction by measuring the spatial and spectral properties of harmonics and electron beams emitted by a plasma mirror. We show that the nanoscale behavior of the plasma mirror can be controlled by tuning the scale length of the electronic density gradient, which is measured in-situ using spatial-domain interferometry.
