Abstract
Interaction of intense laser pulses with plasma finds one of the important applications in acceleration of charged particles. The pioneering work of Tajima and Dawson has given great impetus to the idea of electron acceleration using intense laser pulses. Several experiments and theoretical studies have been done to demonstrate laser wakefield acceleration of charged particles. Acceleration of electrons by amplified wakefield generated by chirped laser pulses propagating together in plasma has also been studied.
Present work deals with the study of slowly varying field generation via propagation of laser pulses in magnetized plasma. This study reveals that the maximum energy gained by test electrons are increases and depends on the amplitude of wakefield. Phase space analysis shows that a test electron of lower energy, injected behind the wakefield, can be trapped and accelerated to higher energy.
