摘要
研究了多光子非线性Compton散射中电子与光子的能量转换及其转换效率 结果表明 :散射光子频率随电子吸收光子数n的增大而增大 ,随碰撞非弹性成分 ξ的增大而迅速减小 在超强激光场中 ,当极端相对论性电子与光子发生多光子非线性Compton散射且被光场俘获时 ,能量转换效率趋于无限大 ,即电子可以从超强激光场中获得巨大的加速能量 用高速电子束入射并与光子发生多光子非线性Compton散射 。
The energy conversion between an electron and photons in multi-photon nonlinear Compton scattering is studied. An expression for the energy conversion efficiency between a relativistic electron and photons is derived. It is shown the frequency of scattered photon is increased by the electron absorption photon number n increase, and it is quickly reduced by collision no elastic ξ increase between electron and photon. In extra-intense stationary laser field, when multi-photon nonlinear Compton scattering is token between relativistic electron and photons, and electron is captured by the laser field, electron energy conversion efficiency will be a ∞, and the energy conversion efficiency can be greatly increased under high-speed electrons incidence, and multi-photon nonlinear Compton scattering conditions.
