This paper discusses the soliton propagation regime of a laser pulse consisting of optical ordinary and terahertz extraordinary components in optically uniaxial media that contain nonsymmetrical resonance nanoobjects of the type of quantum filaments. The treatment takes into account dipole-dipole interaction between the nanoobjects. The conditions are explained under which a terahertz pulse can be efficiently generated when a near-IR optical signal is supplied to the input of the medium. It is shown that this generation process is accompanied by displacement of the spectrum of the optical component into the red region, with this displacement increasing as the pulse width becomes shorter.
