Abstract:

During the reporting period we have developed the mathematical algorithms and programs for the study of the femtosecond pulse propagation in an extended medium of the two-level atoms. The regime of the inversionless superradiance in the two component superradiance medium has been investigated. It has been described the spatio-temporal nonlinear dynamics of coherent field in periodic resonant structures with arbitrary modulation of atomic density and gain gratings.
