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.
