Abstract

The laser wakefield acceleration (LWFA) is a highly significant phenomenon within the realm of high-energy physics and the study of interactions between lasers and plasmas. This research is aimed at conducting a thorough comparative analysis of two distinct pulse shapes, namely, Gaussian and sinh-Gaussian, in order to examine their individual effects on the production and propagation of wakefield in plasma. The research utilizes analytical techniques to evaluate the wake potential, wakefield, and electron energy gain that are produced. The research findings demonstrate that the selection of pulse form has a substantial impact on the development of wakefield and their corresponding characteristics. The utilization of a sinh-Gaussian pulse with a greater decentered parameter (b = 2) is deemed highly appropriate for the purpose of wakefield creation and the subsequent augmentation of electron energy. It provides valuable insights for researchers who are interested in fully utilizing laser-driven plasma wakefield for a variety of applications, including high-energy particle accelerators and compact radiation sources.
