Abstract: The comparison of optical clocks from ground to space will provide unprecedented tests of fundamental physics. Such comparison is limited, though, by the relative motion between the clocks. The experiment in this Letter demonstrates a method to compensate for Doppler shifts over a rapidly moving free-space optical drone link, using an electro-optic modulator. The authors demonstrate Doppler-shift compensation up to 18 MHz, providing a path toward ground-to-space optical comparison.
