AI 中文摘要
通过逆康普顿散射产生强X射线辐射、探索量子电动力学（QED）的强场区域，需要对紧密聚焦的反向传播强激光脉冲进行精确的时空同步。我们提出了一种在该几何结构中建立时空同步的方案，结合了基于显微镜的目标定位、波前传感器辅助的离轴抛物面反射镜对准，以及基于干涉的高分辨率时间延迟扫描。我们观测到72 fs的干涉窗口，与预期的自相关宽度吻合良好。文中讨论了使用该方案在空间和时间上的精度水平。
英文摘要
Generating intense x-ray radiation via inverse-Compton scattering and exploring the strong-field regime of QED, require precise spatio-temporal synchronization of tightly focused counter-propagating intense laser pulses. We present a protocol for establishing spatio-temporal synchronization in this geometry that combines microscope-based target positioning, wavefront-sensor-assisted alignment of off-axis parabolic mirrors, and a high-resolution temporal delay scan based on interference. We observed an interference window of 72 fs in good agreement with the expected autocorrelation width. The accuracy levels in space and time of using this protocol are discussed.
