Ultrafast Kapitza-Dirac effect

Kang Lin, S. Eckart, Hao Liang +8 more

Similar to the optical diffraction of light passing through a material grating, the Kapitza-Dirac effect occurs when an electron is diffracted by a standing light wave. In its original description, the effect is time independent. Here, we extended the Kapitza-Dirac effect to the time domain. By tracking the spatiotemporal evolution of a pulsed electron wave packet diffracted by a 60-femtosecond (where one femtosecond = 10 −15 seconds) standing wave pulse in a pump-probe scheme, we observed time-dependent diffraction patterns. The fringe spacing in the observed pattern differs from that generated by the conventional Kapitza-Dirac effect. By exploiting this time-resolved diffraction scheme, we can access the time evolution of the phase properties of a free electron and potentially image ionic potentials and electronic decoherences.

Kapitza—Dirac diffraction of atoms

Andrei V. Turlapov

Kapitza and Dirac predicted the diffraction of an electron on a standing optical wave.The roles of light and matter here changed places relative to classical optics.Later, ideas about the diffraction of matter on an electromagnetic wave were developed in atomic physics.The diffraction of atoms has been observed in various forms and is used in atomic interferometers.
