拉曼X射线自由电子激光的设想

Proposal for a Raman X-ray Free Electron Laser

Philippe Balcou

摘要:

本文提出了一种X射线自由电子激光方案,它是基于中等相对论性的自由电子束与双强短脉冲激光相互作用过程中产生的喇曼过程,并沿电子轨迹干涉形成横向驻波。在高强度的Kapitza-Dirac效应中,激光有质动力势迫使电子进行横向振荡运动,导致拉曼散射过程。我展示了如何触发一个参数过程,导致拉曼散射光子的斯托克斯分量的放大。实验操作参数和实现,基于LINAC和激光尾场加速技术,进行了讨论。

英文摘要:

A scheme for an X-ray free electron laser is proposed, based on a Raman process occurring during the interaction between a moderately relativistic bunch of free electrons, and twin intense short pulse lasers interfering to form a transverse standing wave along the electron trajectories. In the high intensity regime of the Kapitza-Dirac effect, the laser ponderomotive potential forces the electrons into a lateral oscillatory motion, resulting in a Raman scattering process. I show how a parametric process is triggered, resulting in the amplification of the Stokes component of the Raman-scattered photons. Experimental operating parameters and implementations, based both on LINAC and Laser Wakefield Acceleration techniques, are discussed.
