Abstract

The numerical calculations of the spectrum of nonlinear polarization for 3- and 4-level system in femtosecond pulses have been made. The strong field interaction is responsible for coherence transform, red -, blue shifts and splitting on the spectrum. The reverse Fourier transform for restore of time domain is proposed for dephasing rate determination. The comparison with experimental results for complex molecules and semiconductors has been made.
