摘要

本文推导了在静电场作用下,椭圆极化脉冲隧穿气体电离过程中激发的自由电子电流密度的解析表达式。分析计算了激光脉冲低阶奇偶谐波处电流密度的谱成分,与数值模拟结果吻合较好。

Аналитический расчёт плотности тока свободных электронов на низших гармониках ионизирующего эллиптически поляризованного лазерного импульса в присутствии постоянного электрического поля
The paper presents the derivation of an analytical expression for the current density of free electrons excited during tunneling gas ionization by an elliptically polarized pulse in the presence of a static electric field. The analytical calculation of the spectral components of the current density at the low- order odd and even harmonics of the laser pulse is in good agreement with the results of the numerical simulation.
