分析了相对论强激光脉冲场中电子的辐射。在J ≥ 2x 10（22）W/cm（2）的脉冲强度下，只要电子能量足够高：E ≥ 1 GeV，反向传播电子的发射就会受到量子电动力学（QED）效应的影响。首次从QED原理导出了电子所受的辐射力，并将其适用范围向QED强场扩展。
The emission from an electron in the field of a relativistically strong laser pulse is analyzed. At pulse intensities of J>or=2x10(22) W/cm(2) the emission from counterpropagating electrons is modified by the effects of quantum electrodynamics (QED), as long as the electron energy is sufficiently high: E>or=1 GeV . The radiation force experienced by an electron is for the first time derived from the QED principles and its applicability range is extended toward the QED-strong fields.
