Subjects: Relativistic electrons, Particle acceleration, Laser pulses, Polarization (Electricity), Gaussian beams, Lorentz force
Abstract: In this study, the interaction of electrons with a radial polarized chirped Sinh–Gaussian laser pulse is investigated. Solving Lorentz force equation, coupled differential equations for electron relativistic factor are obtained and solved analytically. This interaction depends on several laser parameters like laser electric field amplitude, decentered parameter, beam waist and frequency chirp parameter. Results show that for higher values of laser electric field, decentered parameter and frequency chirp, enhanced electron energy gain is obtained, while optimization of beam waist is essential for enhanced energy gain. A maximum of 2.34 GeV electrons is obtained by using optimum values of the parameters involved. This study is useful for obtaining electrons with enhanced energy for scientific research, industrial and medical investigations. [ABSTRACT FROM AUTHOR]
