Аналитический расчёт плотности тока свободных электронов на низших гармониках ионизирующего эллиптически поляризованного лазерного импульса в присутствии постоянного электрического поля

Abstract

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.
