Abstract
We show that, in complete analogy to the electron-beam driven Plasma W akefield Accelerator (PWFA), an optimal transformer ratio can be attai ned in the laser driven Laser Wakefield Accelerator (LWFA), by properl y shaping the longitudinal profile of the driving laser pulse. The con cept of transformer ratio in LWFA is introduced and the optimal laser pulse shape is derived in the linear regime of laser-plasma interactio n. We show that in the linear regime of plasma perturbation the requir ement for the laser pulse shape and the resultant optimal transformer ratio are identical for LWFA and PWFA concepts.
