description: The given work is devoted to study the features of two-photon resonance in an optically dense medium, taking into account the diffusion of working atoms. As a result of research in the Matlab environment, a mathematical model of a three-level atom with a Î-excitation scheme was constructed, taking into account the effects of a dense medium and the diffusion of working atoms in a buffer gas medium. Mathematical modeling of the behavior of a three-level system while simultaneously taking into account these effects has not been carried out previously. From this point of view, all the results obtained are new. The population distributions along the cell obtained by simultaneously taking into account diffusion and the dense medium are analyzed. The question of the dependence of the shape of the absorption lines of a gas cell on the concentration of buffer particles, which affects the diffusion coefficient and the frequency of elastic collisions âworker-buffer particleâ, has been studied. To study the issues raised in the work and master the corresponding theoretical base, open educational resources and programs for searching and analyzing information were used.
