Spin polarization of photoelectrons is considered in the ionization of atoms by a laser field and its second harmonic, concentrating on the effects of interference between the two ionization paths. The possibility for a crucial increase of the spin polarization by manipulating the relative phase of the harmonics is demonstrated. Observation of these effects, exemplified by the ionization of neon atoms, is accessible by modern free-electron lasers working in the extreme-ultraviolet wavelength regime.

双色极紫外原子电离中光电子的自旋极化

在通过激光场及其二次谐波使原子电离时,会考虑光电子的自旋极化,重点是两个电离路径之间的干涉效应。通过操纵谐波的相对相位,可以显着增加自旋极化的可能性。这些效应的观察,例如氖原子的电离,可以通过工作在极紫外波长范围内的现代自由电子激光器来观察。
