AC Electric Field
The ionization rate of an hydrogen atom in an alternating electric field, like that of a laser, can be treated, in the appropriate limit, as the DC ionization rate averaged over a single period of the electric fields oscillation. This models was proposed by Keldysh and then later expanded to hydrogen-like atom by A.D.K..

Famous quotes containing the words electric and/or field:
“Wisdom is like electricity. There is no permanently wise man, but men capable of wisdom, who, being put into certain company, or other favorable conditions, become wise for a short time, as glasses rubbed acquire electric power for a while.”
—Ralph Waldo Emerson (1803–1882)
“And there, a field rat, startled, squealing bleeds,
His belly close to ground. I see the blade,
Blood-stained, continue cutting weeds and shade.”
