Description
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 wakefields by propagation intense laser pulse in plasma (LWFA). Several experiments have been done to demonstrate laser wakefield acceleration of charged particles. Acceleration of electrons by enhanced wakefield generated by two laser pulses propagating together in plasma has also been studied.
Present paper deals with the wakefield generation by propagation of two-colour asymmetric laser pulses in cold, underdense and homogeneous plasma. Further, acceleration of electron is studied in enhanced wakefield. This study reveals that the maximum energy gained by test electron is enhanced and depends on the wakefield amplitude which in turn depends on the skewness of the two laser pulses. Phase space analysis shows that a test electron of lower energy, injected in the wakefield, can be trapped and accelerated to higher energy.
