Propagation characteristics of a high-power beam in weakly relativistic-ponderomotive thermal quantum plasma

Abstract

The present work explores the propagation characteristics of high power beam in weakly relativistic-ponderomotive thermal quantum plasma (TQP). Q-gaussian laser beam is taken in present investigation. The quasi optics equation obtained in present study is solved through well established WKB approximation and paraxial theory approach for obtaining 2nd order differential equation describing the behavior of beam width of laser beam. Further, numerical simulation of this 2nd order differential equation is carried out for determining the behavior of beam width with dimensionless distance for established laser-plasma parameters. The comparison of present study is made with ordinary quantum plasma and classical relativistic plasma cases

The combined effects of quantum and strong coupling on the nonlinear collective excitation in quantum dusty plasmas

“…e i e i Fe,Fi 2 2 , 2 3 , p =  ( ) being the Fermi energy, where e is the electron charge, n e,i is the number density of electrons or ions, m e,i is the rest mass of electron or ion, and ÿ is the reduced Plancks constant. The qantum coupling parameters of electrons and ions implies that a quantum plasma becomes even more ideal at higher densities [11][12][13]. The quantum diffraction effect stands for the fluctuation of microscopic particles, which was experimentally verified by x-ray Thomson scattering [14].…”

The influence of a self-focused laser beam on the stimulated Raman scattering process in collisional plasma

“…-[1, 2]. Several researchers have been investigating the interaction of intense lasers with plasmas due to its applicability to distinct applications, such as inertial confinement fusion, particle acceleration and relativistic nonlinear optics [3][4][5][6][7][8][9][10][11][12][13][14][15]. Success can be achieved in these applications on the basis of deeper laser beam transition through plasmas.…”
