摘要
研究了相刘沧性电子在强激光场中的非线性康普顿散射，进而导出散射光子频率的表达式．结果表明：当散射角为0时，电子仪仪充当了“耦合器”的作用，并存在n倍频效应．当散射角为π时，若电子和光子对撞，散射光子的频率随电子吸收光子数n的增大而增大，随激光场强度增强而减小；若光子追上电子而发生碰撞且散射光子被反弹时，可实现激光场对电子的有效加速．
Nonlinear Compton scattering in the interaction of relativistic electron with intense laser fields is investigated, and the expression of the scattered - photon frequency is deduced. It is shown that the relativistic electron only acts as a couple and the n -times -frequency effect will happen when the scattering angle equals to zero. The frequency of scattered photon increases with the increase of absorbed photons and decreases with the laser fields intensity enhances when relativistic electron collides with photons in the opposite direction. When relativistic electron collides with photons in the same direction and the scattered photon rebounds, accelerating electron effectively by laser field can be realized.
