Results of the complex experimental study of the spectral and temporal characteristics of the emission glow of control samples of several substances in the solid state (imitation of topographic targets in the atmosphere) and in the form of solid aerosols (imitation of air pollutants) under the action of femtosecond pulses of a Ti:Sa laser (at a carrier wavelength of 800 nm) and nonlinear optical effects are presented.
