Abstract

Results are presented of theoretical studies into the resonances of the saturated absorption and saturated dispersion in an external absorption cell The theory has been worked out by means of combining methods of mathematical theory of diffraction and quantum mechanical method for computing the polarization of active media This made it possible for the first time to find a self-consisting spatial solution of the density matrix equation for the two-level system and the Helmholtz equation for electromagnetic field and to solve the problem of propagation of two counterpropagating monochromatic waves though an absorption nonlinear medium taking into consideration the transverse transit-time effect
