Abstract: The transparency modes, taking place during the electromagnetic pulse propagation in the media of anisotropic quantum objects, were studied. It was considered the case of perpendicular to the optic axis propagation of the pulse, when the resonant pulse constituents induce the quantum transitions, and the low frequency extraordinary component produces the frequency shift of these transitions. It was found out that the pulse propagation mode is mainly determined by the prevailed component. It was shown that regimes of self-induced and extraordinary transparencies are possible in case of $V$-scheme of quantum transitions. The last is characterized by the domination of extraordinary component, the trapping of the population effect and the strong decrease of the pulse velocity. At the same time the electromagnetic transparency mode is possible in the case of $\Lambda$-scheme.
