Abstract
A theory has been developed for the nonsteady-state absorption of supershort light pulses in bulk materials and heterostructures with quantum wells when two-photon resonance occurs at interband transitions as well as at transitions between discrete states or between size-quantization sublevels (subbands). Analytical expressions have been obtained for the nonlinear polarizabilities that determine how much energy is absorbed from a femtosecond light pulse. The dependences of the absorbed energy on the detunings of the two-photon resonances and on the pulse widths have been obtained.
