平滑激光脉冲诱导的阈上离化

ABOVE-THRESHOLD IONIZAT1ON BY A SMOOTH LASER PULSE

阈上离化(above-threshold ionization)是近年来发现的一种新现象。本文在基本态模型基础上利用非微扰理论研究了高斯型激光脉冲诱导的阈上离化,讨论了其特征光电子能谱随时间的演化。

In this paper, using 'essential states model' we present an non-perturbative analysis of above-threshold ionization by a Gaussian laser pulse, and discuss the time evolution of its characteristic electron spectra.
