Description 897-902
The propagation of Lorentz-Gauss (L-G) Laser beam in collisionless plasma is investigated. Based on WKB and paraxial
approximations, coupled differential equations for beam-width parameters in two transverse dimensions of L-G beam are
derived under the parabolic equation approach. The self-focusing and self-defocusing characters of L-G beam are
numerically demonstrated. The influence of Lorentz width on the propagation of L-G beam through plasma is specifically
considered. It is found that the heterogeneous intensity distribution of L-G beam plays a vital role in its propagation
dynamics through plasmas.
