摘要: 提出了一种由超短脉冲双光束担任摇摆器的自由电子激光器的原理及设计方案,并在单电子近似的基础上给出了计算其增益的联立方程组,以用于数值模拟.指出了实现一种紧凑、廉价的可调谐光源的可能性.

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.
