Abstract

Thanks to advancements such as chirped pulse amplification (CPA), the peak power of lasers has reached the petawatt level. Accurately measuring the parameters of ultra-intense and ultra-short laser focal spots is crucial for providing fundamental theoretical explanations for strong-field physics experiments, and it holds significant importance for research in strong-field laser physics and related technological applications. Based on the theory and numerical simulations of vacuum laser-driven electron acceleration, this study reports a high-precision method for measuring laser focal spot parameters by analyzing the scattering angles and energy data of scattered electrons.

基于激光加速电子的超强激光焦斑参数表征
由于啁啾脉冲放大(CPA)等技术的进步,激光的峰值功率已经达到了千瓦级。准确测量超强超短激光焦斑参数,对于强场物理实验提供基础理论解释至关重要,对强场激光物理研究及相关技术应用具有重要意义。本文在真空激光驱动电子加速理论和数值模拟的基础上,提出了一种通过分析散射电子的散射角和能量数据来高精度测量激光焦点光斑参数的方法。
