摘要: 为了研究Compton散射对强激光等离子体中辐射阻尼效应的影响，采用多光子非线性Compton散射模型、相对论理论和洛伦兹变换方法，对Compton散射对不同极化激光在等离子体中产生辐射阻尼效应的影响进行了理论分析和数值计算。提出了将Compton散射光作为等离子体产生辐射阻尼效应的新机制，给出了辐射阻尼满足的修正方程。结果表明，Compton散射使等离子体辐射阻尼效应对电子运动产生重要作用的几率增大，这主要是由于产生这种作用所需的入射激光强度降低，从而使电子频率增大、电场耦合频率增大的缘故。多光子非线性Compton散射光是产生和提高等离子体辐射阻尼效应的一个重要机制。

Abstract: In order to study effect of Compton scattering on the radiation damping effects in ultra-intense laser plasma, the effect of plasma induced by different polarized lasers was analyzed and calculated based on the model of multi-photon nonlinear Compton scattering, relativity theory and Lorentz transformation. The new mechanism of the radiation damping effect induced by Compton scattering in plasma was presented and the revised equation on the radiation damping effect was put forward. The results show that the probability of electron movement is increased because the required incident laser intensity is reduced and then the electron frequency and the coupling frequency of the electric field are increased. The multi-photon nonlinear Compton scattering is an important mechanism on taking and increasing the radiation damping effect of plasma.
