摘要
We present calibrated measurements of single-photon Thomson scattering from free electrons driven by a laser with intensity 10(18) W/cm(2). The measurements demonstrate that individual electrons radiate with the strength of point emitters, even when their wave packets spread to the scale of the driving-laser wavelength. The result agrees with predictions of quantum electrodynamics. (C) 2016 Optical Society of America
