A comparative study of laser wakefield produced by Ti: sapphire laser, Nd: YAG laser and CO₂ laser under identical conditions

This paper presents a comparative analysis of laser wakefield acceleration (LWFA) generated by three different laser systems; Ti: Sapphire, Nd: YAG, and CO₂ lasers, operating under identical conditions. Laser wakefield acceleration, a promising technique for compact particle acceleration, relies on the interaction of intense laser pulses with a plasma medium to generate high-energy electron beams. By conducting an analytical study with three distinct laser systems at similar plasma parameters, we aim to investigate the influence of laser wavelength on the resulting electron beam characteristics. Our findings reveal a significant increase in the wake potential, wakefield and electron energy gain produced by each laser system with the increase in the wavelength of used laser pulse. This comparative analytical study provides valuable insights into optimizing laser parameters for tailored electron beam generation in laser wakefield acceleration experiments.
