چکیده انگلیسی
Guiding of laser beam in plasma channel formed by short ionizing laser pulse is studied in this paper. When a delayed pulse propagates through this channel diffraction, refraction and self-phase modulation phenomena results which are not balanced resulting in increase/decrease in beam width. These are studied using direct Variational Technique. In this paper cross-focussing phenomena is not observed. Parameters like beam width and longitudinal-phase delay of elliptical laser beam are also studied. It has been observed that the propagation of semi-major axis and semi-minor axis of elliptical beam are independent leading to oscillating guided beam.
