Abstract
The study of self-compression of laser pulse having super-Gaussian profile in relativistically guided plasma has been investigated. A nonlinear propagation equation of laser pulse in plasma using relativistic nonlinearity has been derived. Moreover, a semi-analytical method was used to solve the nonlinear equation for self-compression and self-focusing of the laser pulse in plasma. It has been seen that pulse broadening and relativistic nonlinearity are sole origin for self-compression of Super-Gaussian laser pulse inside the plasma. The pulse broadening accure due to effect of group velocity dispersion (GVD) and when, nonlinearity combined (balanced) with it pulse broadening, result in formation of compressed and amplified pulse in enhance manner. Numerical computation result shows that, a 50 fs laser pulse gets compressed into 17 fs laser pulse.
期刊介绍：
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
