Abstract

Laser wakefield acceleration is one of the prominent methods to obtain high energy charge particles. This method can be used to accelerate lighter charged particles like electrons to relativistic energy level. Energy enhancement of electrons depends on the properties of laser pulse as well as plasma. In this study, we have used a circular polarized laser pulse propagating (along z- axis) through under-dense plasma. An external oblique transverse static magnetic field is applied an arbitrary angle (at angle \(\uptheta\) with Y-axis in x–y plane). Effect of laser pulse strength (\(a\)), strength of external magnetic field (\({B}_{0}\)), and its arbitrary angle (\(\uptheta\)) on generated longitudinal wakefield, wake potential, change in relativistic factor and energy enhancement are calculated theoretically and curves are drawn. Optimized oblique angle for maximum wakefield and potential is calculated for selected parameters. This study is useful for obtaining an energy efficient acceleration technique for electron.
