Abstract
A theory of the transient absorption of femtosecond light pulses at a two-photon–one-photon double resonance on adjacent interband transitions in the electronic system has been developed. Approximate expressions for the reactive component of the nonlinear polarization of the three-level system, Ps, which determines the absorbed power in the medium, have been obtained, and the dependences of Ps on the light intensity and detunings of resonances have been calculated.
