Abstract
In this paper,we proposed a novel free electron laser(FEL), using two ultra-short laser pulses as a wiggler,instead of conventional wiggler coil.A single particle approach has been used to derive the gain equations at the fundamental harmonic in this construction.According to this proposal,it is possible to manufacture a compact a low-priced FEL.
