摘要
应用相对论性电子与多光子集团非弹性碰撞模型和经典相对论电动力学理论,分析、计算了锥形飞秒强激光等离子体中多光子非线性Compton散射的能量转换.发现等离子体中的耦合激光场会引起能量转换效率的振荡,而静电场会降低能量转换效率.当高能电子与光子发生双光子非线性Compton散射时,电子能获得最大的能量转换效率.
The energy conversion efficiency of the multi-photon nonlinear Compton scattering in the cone-shaped femto-second high power laser-plasma is given by using the inelastic collision model of relativistic electron and photon, and relativistic electricity theory. We find that the vibration of the electron acceleration energy is takenplace by the coupling laser field in the laser-plasma, and the energy conversion efficiency is lowered by the electrostatic field. The greatest energy conversion efficiency of the electron has been worked out by using the two photons nonlinear Compton scattering of the high-energy electron with photons in the cone-shaped femto-second high power laser-plasma.
