Electron dynamics in a strong laser field

Languages of publication
The three step model of high harmonic generation was used to investigate the electron behaviour in a strong laser field. The electron propagation was analyzed classically and the electron recombination with the parent atom was analyzed quantum mechanically. Three laser fields Argon with 500 nm, Helium-Neon with 632.8 nm and Ti-Sapphire with 800 nm wavelengths were used to analyze the electron behaviour for different intensities and the electron propagation was analyzed in cosine and sine electric laser fields. For a strong applied laser field, the atomic potential get distorted and the barrier potential is reduced. The maximum kinetic energy of the emitted electron, the ponderomotive energy was 8Up in both cases and there were three points which gave the maximum kinetic energy for the laser field with sine electric field. When the laser intensity was increasing, the electron has a higher probability to move away from the parent atom. When the laser field changed its direction, electron recombined with the parent atom with a maximum kinetic energy of 3.17Up.
