Paper Abstract

A method of integrodifferential equations associated with the optical Bloch equations is used to consider the boundary-value problem of nonlinear reflection (refraction) of the laser beams on the superthin film doped by the two-level atoms. An allowance is made for the phase memory effects exhibited by two-level atoms in response to pulses of fields resolved in space and time. A generalized Lorentz-Lorenz formula is derived for a nonlinear complex refractive index of an doped film in the region of an absorption band when this index depends nonlinearly and nonstationarly on the field inside the film. We derived generalized synchronism conditions to investigate the angular distribution of reflected and refracted primary photon echo signals.
