本文报道了椭圆偏振光非线性汤姆逊散射的实验结果。作为入射激光椭圆偏振态的函数，测量了散射光的偏振分辨辐射模式。在强椭圆极化场中的相对论电子轨迹导致了独特的辐射极化态的形成，这是我们通过测量和理论模型所观察到的。汤姆逊散射光的偏振很大程度上取决于入射光的强度。这些结果与高场电动力学和具有新性能的光源的研究和开发有关。
We report experimental results from a study of nonlinear Thomson scattering of elliptically polarized light. Polarization-resolved radiation patterns of the scattered light are measured as a function of the elliptical polarization state of the incident laser light. The relativistic electron trajectory in intense elliptically polarized fields leads to the formation of unique radiated polarization states, which are observed by our measurements and predicted by a theoretical model. The polarization of Thomson scattered light depends strongly on the intensity of the incident light due to nonlinearity. The results are relevant to high-field electrodynamics and to research and development of light sources with novel capabilities.
