The methodology, technique, and results of studies of the formation of films on the glass surface during the irradiation of water solutions of copper sulfate with the laser radiation are presented. We used the nanosecond radiation of an yttrium-aluminum garnet laser with the generation wavelength λ = 1 .06 μm. The studies used solutions with different concentrations of copper sulfate. The structure of the films obtained in this case is compared with the structure of the films obtained as a result of drying the solutions without exposure to a laser radiation. The resulting films have both ordered and disordered structures. The characteristic dimensions of the structural elements of the films are 0.5–2 μm. The transmission of films in the 300–1200 nm spectral region is studied. In general, the resulting films are transparent in this area. Their transmission practically does not depend on the wavelength, but is different for different concentrations of the solution of copper sulfate.
