标题： Optimizing the incident electron momentum for resonant few-photon Kapitza-Dirac scattering in bichromatic laser fields

摘要： 非相对论性电子在反向传播的双色激光波中的Kapitza-Dirac散射在共振布喇格区域被研究，同时考虑了电子自旋的影响。 我们表明，在电子初始态和散射态之间的Rabi振荡动力学中出现的固有场诱导失谐，可以通过适当调整其入射动量来补偿。 从保持该过程特征性质的简化低维模型系统中，得到了用于自旋依赖的三光子和自旋无关的四光子Kapitza-Dirac散射的优化电子动量的解析公式。 显示英文摘要

摘要： Nonrelativistic Kapitza-Dirac scattering of electrons from counterpropagating bichromatic laser waves is studied in the resonant Bragg regime, taking the electron spin into account. We show that the intrinsic field-induced detuning, which arises in the Rabi oscillation dynamics between initial and scattering state of the electron, can be compensated by a suitable adjustment of its incident momentum. Analytical formulas of the optimized electron momentum for spin-dependent three-photon and spin-independent four-photon Kapitza-Dirac scattering are obtained from simplified model systems in reduced dimensionality, which preserve the characteristic properties of the process.
