Abstract
Probabilities of n-photon transitions between upper valence and lower conduction bands under conditions in which the frequency of light is in resonance with the frequency of adjacent transition between two conduction bands are calculated for arbitrary integer n. The case of n = 3 is investigated in detail. Effects caused by transformation of the electronic band spectrum due to the resonance optical Stark effect are analyzed. It is shown that the rate of photogeneration of electron-hole pairs as a function of radiation intensity j is nonmonotonic and includes areas of extremely fast rise and/or decrease due to the appearance of new van Hove singularities in the modified band spectrum.
