Exploring the potential of cosh-Gaussian pulses for electron acceleration in magnetized plasma

This work investigates the acceleration of electrons in a homogeneous magnetized plasma that is both cold and collisionless. We obtained an increase in energy by stimulating laser wakefield excitation using a cosh-Gaussian laser pulse. The analysis shows a significant rise in both wakefield excitation and maximum gain in electron energy with increasing pulse strength. The amount of the external magnetic field, pulse length, and parameter \({w}_{0}\) $w_0$ are essential for achieving higher acceleration and a greater amplitude wakefield, together with pulse intensity. By carefully adjusting these various parameters, we can create a very powerful wakefield for accelerating electrons. By utilizing precise normalized parameters, we have successfully attained an energy gain of up to 433.80 MeV in this study. The findings of this study on laser-driven electron acceleration may be valuable for researchers involved in the rapidly advancing field of laser science and technology.
