This research article investigates the optimization of laser-driven electron acceleration using sinh-squared Gaussian laser pulses. The study focuses on analyzing the wake potential, wakefield, and electron energy gain generated by such pulses in underdense plasma. The results show that the wake potential, wakefield, and electron energy gain are directly proportional to the square of the laser field amplitude. An increase in plasma density leads to a damped oscillatory change in energy gain. The study also examines the impact of pulse length and sinh-squared Gaussian parameters on energy gain, determining optimal values for these parameters. The optimal values yield a maximum energy gain of 1.7 GeV. The findings will assist researchers in selecting appropriate pulse profiles for energy-efficient electron acceleration. Laser wakefield acceleration (LWFA) is a prominent method for electron acceleration using intense laser pulses in underdense plasma. The efficiency and energy gained by electrons depend on various parameters of the laser and plasma. Previous studies have explored the effects of frequency chirp, pulse length, plasma density, and external magnetic fields on electron energy gain. Different laser pulse profiles, such as Gaussian, super-Gaussian, and cosine-Gaussian pulses, have been studied for their impact on electron acceleration. In this study, a sinh-squared Gaussian laser pulse is used to generate laser wakefield, wake potential, and electron energy gain in underdense plasma. The analytical solutions of wakefield, wake potential, and electron energy gain are derived for this pulse profile. The results are discussed in terms of the effects of various parameters on energy gain. The study concludes that the sinh-squared Gaussian pulse profile is effective for achieving energy-efficient electron acceleration.This research article investigates the optimization of laser-driven electron acceleration using sinh-squared Gaussian laser pulses.
