Strong Field Autoionization in Time-Dependent Fields

Autoionization resonances are intensively investigated both experimentally and theoretically. A lot of attention has been devoted recently to a theoretical study of the strong field ionization to an autoionization resonance. (For the extensive list of references see1.) However attempting to approach a physically realizable conditions by inclusion of: a finite width of the phase fluctuating laser light, an inhomogeneous broadening, a pontaneous emission, the existence of other atomic levels and continua, all these papers remain unrealistic in one important respect: They all assume a sudden switching — on of the strong laser signal, which otherwise remains time independent.
