聚焦laser脉冲非线性康普顿散射的高分辨率模拟

High-resolution modeling of nonlinear Compton scattering in focused laser pulses

Christian F. Nielsen, Robert Holtzapple, Ben King

摘要:

用半经典方法计算了电子与强聚焦激光脉冲碰撞的辐射发射。结果进行了比较,从本地恒定场和本地单色近似的预测。结果发现,模拟采用半经典的方法捕捉功能的能量谱,如次谐波和带宽结构,这是超越本地的方法。引入形成长度作为诊断,以在电子通过脉冲传播时在方法之间进行选择。

英文摘要:

A semi-classical approach is used to calculate radiation emission in the collision of an electron with an intense focused laser pulse. The results are compared to predictions from the locally constant field and locally monochromatic approximations. It is found that simulations employing the semi-classical approach capture features in the energy spectra, such as subharmonics and bandwidth structure, which are beyond local approaches. The formation length is introduced as a diagnostic to select between approaches as the electron is propagated through the pulse.
