摘要
借助当今的百兆瓦激光，测试强场极限下的量子电动力学（QED），即电场在电子静止系中的斯波igner 临界场强以上，已进入可实现阶段。逆康普顿散射将强激光脉冲射向高能电子束，是产生高能光子的主流方法，这些光子可衰变为贝里特-沃勒电子-正电子对。本文表明，在自对齐单激光康普顿散射 setup 中，可实现高能光子的产生，该 setup 结合了激光-等离子体加速器和等离子体镜。光子能量可达 GeV 级，基于非线性康普顿散射的光子发射在实验中表现出非经典的标度，与电场达到电子静止系中斯波igner 场强约 的结果一致。通过自动激光-电子重合保证的可靠碰撞，为精确探索强场 QED 过程提供了新的方法。
