Effects of plasma and ultrashort laser pulse on residual electron energy in optical-field-ionized oxygen plasma

摘要

In this paper the classical theory of Above Threshold Ionization (ATI) in the oxygen plasma was used to show how the residual electron energy depends on the laser parameters such as pulse length, wavelength and peak intensity. The value of ATI energy is found to increase with laser wavelength and its intensity. Our study conducted for three cases of τ? >? 2π/ν p, τ? =? 2π/ω p, and τ?
