The possibility is considered of creating, based on nonlinear crystal optics, an all-solid-state source of coherent radiation in the region of 0.2 to 12.0 mkm intended for use in a general-purpose gas-aerosol lidar. It is shown that the use of parametric frequency converters of Nd:YAG, holmium, and erbium laser radiation enables one to develop such a source with the parameters meeting its practical implementation. For the mid-IR region we propose to use nonlinear HgGa2S4 crystals, doped GaSe:In crystals, and new AgGaxGe1-xS4 and Hg(1-x)CdxGa2S4 mixed crystals that have been poorly studied yet. Some results of a thorough research of the linear and nonlinear optical properties of these crystals are presented. In the rest part of the region considered, it is proposed to use commercial frequency converters based on LBO, KTA, KTP, and BBO crystals.
