laser场通过原子ATI态产生多电荷离子的绝热机制
Adiabatic mechanism of the multiply charged ion production by a laser field through ATI states of an atom
摘要：
ATI之后可以是电离电子与母原子粒子的非弹性碰撞，导致离子的激发。它可以是产生双电荷离子的连续态激发或也增强双电荷离子产生的离散态激发。吸收原子阈值以上的几个量子就足以使这种机制起作用。因此，即使在中等的电场中，双电子过程也能发生。本文讨论了He原子在780 nm激光场中的双电子激发，激光强度大于$ 10^{14}$ W/cm $^2$
英文摘要：
ATI can be followed by an inelastic collision of the ionized electron with the parent atomic particle resulting in an excitation of the ion. It may be a continuum state excitation producing the doubly charged ion or a discrete state which also enhances the doubly charged ion production. Absorption of a few quanta above the atomic threshold is sufficient to make this mechanism work. As a result the two-electron processes can take place even in moderate fields. The example of two-electron excitations of He atoms in a 780 nm laser field with intensity above $ 10^{14}$W/cm$^2$ is discussed
