The energy flux density of the incident light upon the crystal surface and the form of the wave packet envelope with frequencies lying in the exciton range of the spectrum, are determined. They must be of such a nature that after the penetration into the semi‐infinite crystal, the laser pulse can travel at once as a solitary wave without any transient stage. In the case considered the effect of the dipole momentum saturation (DMS) for the transition from the ground state of the crystal to that of the exciton is the main nonlinearity. The Maxwell‐Fresnel boundary conditions are used on the interface between the vacuum and the crystal.
