Parametric Dispersion of Acoustic Wave in a Laser Irradiated Semiconductor Plasma: Quantum Effects
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 6
Abstract
Quantum hydrodynamic model for one component plasma along with coupled mode theory is used to study dispersion characteristics of acoustic wave in a laser irradiated semiconductor plasma medium. Dispersion effects are explored in this paper through second order susceptibility of the medium which is a measure of the strength of second order nonlinear interaction. Dispersion characteristics are found to be effectively modified through quantum effects. It is found that doping concentration and pump field amplitude could be used to tune the dispersion characteristics of acoustic wave. Positive and negative magnitudes of real part of second order susceptibility are favourable for self-focusing and defocusing of laser light. It can be envisaged that a practical demonstration of the above kind of parametric dispersion may lead to the possibility of observation of group velocity dispersion in semiconductor plasma medium by considering a small degree of phase mismatch.
