Abstract

A three-dimensional envelope equation was derived to evaluate the stability properties of intense laser pulses propagating extended distances in tapered plasma channels. A laser wakefield accelerator (LWFA) was used to investigate the required conditions to achieve multi-GeV electron energies in laser pulse propagation. The analysis showed that increasing plasma density as a function of distance could make phase velocity of the accelerating field behind the laser pulse equal to the speed of light. It was found that pulse shape determined the seed for instability growth for both long and short pulses.
