报道了超强(~gt；或=10(19)W/cm2)激光脉冲辐照金属箔靶中电子横向输运的实验研究。二维空间分辨离子发射测量被用来量化电子传输产生的电场。对距离激光焦点约0.1TV/m的大电场的测量表明，横向能量传输在激光脉冲衰减后很长时间内仍在继续。数值模拟证实，靶边缘的电子密度和电场有很强的增强。
An experimental investigation of lateral electron transport in thin metallic foil targets irradiated by ultraintense (>or=10(19) W/cm2) laser pulses is reported. Two-dimensional spatially resolved ion emission measurements are used to quantify electric-field generation resulting from electron transport. The measurement of large electric fields ( approximately 0.1 TV/m) millimeters from the laser focus reveals that lateral energy transport continues long after the laser pulse has decayed. Numerical simulations confirm a very strong enhancement of electron density and electric field at the edges of the target.
