- Title
A transient two-photon-one-photon double resonance on interband transitions in crystals: I. General relations.
- Authors
Bondarev, M.; Perlin, E.
- 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, P , which determines the absorbed power in the medium, have been obtained, and the dependences of P on the light intensity and detunings of resonances have been calculated.
