Kapitza-Dirac scattering of electrons from a bichromatic standing laser wave
摘要：
本文研究了电子束在激光驻波中的Kapitza-Dirac相干散射。为此，薛定谔方程数值求解与适当的有质动力势。此外，还得到了大振幅场渐近域中电子衍射的解析解，并给出了布拉格区散射振幅的降维数学模型。当驻波包含一个基频和它的二次谐波时，我们展示了不同的干涉特征和相对相位效应。讨论了相对场强对拉比振荡动力学的影响。
英文摘要：
Coherent scattering of an electron beam by the Kapitza-Dirac effect from a standing laser wave which comprises two frequency components is studied. To this end, the Schrödinger equation is solved numerically with a suitable ponderomotive potential. Besides, an analytical solution for electron diffraction in the asymptotic domain of large field amplitudes is obtained and a mathematical model in reduced dimensionality for the scattering amplitude in the Bragg regime is presented. We demonstrate distinct interference signatures and relative phase effects when the standing wave contains a fundamental frequency and its second harmonic. The influence of the relative field intensities on the Rabi oscillation dynamics is also discussed.
