Numerical Simulation of Coherent Extreme Ultraviolet Radiation by Considering Simple Hydrogen Atomic Potential
Abstract
In this study, the ionization of a single electron exposed to an intense laser field is computed, and the nonlinear dipole response of a single electron is obtained. The ionization of a single electron exposed to an intense laser field can be computed using the strong field approximation (SFA), also known as the Keldysh theory. This method is based on the idea that the laser field is so strong that it can ionize the electron by tunneling through the Coulomb barrier. In this paper, the Xe, Ne, and H2 gas species are modeled since they have simple atomic systems. All gas species have relative or close ionization potentials. Ultra-short pulse duration (50 fs) is accepted because of the shorter time scale than the electron energy-lattice transfer. The ionization potentials of gas species result in the Keldysh parameter being smaller than one. The electron dipole oscillation spectra of these gas species are simulated by calculating the dipole spectrum considering the Lewenstein model. The electron propagation under the different wavelengths is simulated. The effects of the different driving wavelengths have noticeable effects on the enhancement and the extension of the extreme ultraviolet radiation signal.
