Description
The large energy spread and divergence of the electron beam produced currently in laser-driven wakefield accelerators could dramatically reduce the gain amplification expected in LWFA-based free electron lasers . Single beam decompression stage or transverse gradient undulator have been proposed to cope with the large energy spread. Another method based on a further beam manipulation has been proposed to recover high FEL peak power despite the large initial energy spread and divergence of the electron beam . Results of particle tracking and FEL process simulation will be also presented.
