“…The polarization of laser radiation was linear. After exiting the amplifying stage, the laser radiation was directed vertically down onto stage (5 ) with the help of rotating prism (4 ). On it was placed glass plastic (6 ) with two drops (7 ) and ( 8) of an aqueous solution of copper sulfate of the same concentration, almost identical in volume and size.…”

“…bents, catalysts, fillers of composite materials, membranes, and in a number of other small-scale systems with quantum effects [1]. The creation of such structures on the surface of dielectrics and metals is carried out by various chemical and physical methods [2][3][4][5][6][7][8][9][10][11][12][13][14]. Among the physical methods of structuring the surface of metals, dielectrics, and semiconductors, a special place is occupied by laser methods, whose radiation of nano-pico-or femtosecond duration directly acts on the surface of a solid structure in air or another gaseous medium [10][11][12][13].…”

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.

“…Micro-and nanostructures synthesized on the surface of solids are now widely used in highly dispersed systems, in particular, adsorbents, catalysts, fillers of composite materials, membranes, and a number of other low-dimensional systems with quantum effects [1]. The creation of such structures on the surface of dielectrics and metals is carried out by various chemical and physical methods [2][3][4][5][6][7][8][9][10][11][12][13][14]. Among the physical methods for structuring the surface of metals, dielectrics, and semiconductors, a special place is occupied by laser methods, when nano-, pico-or femptosecond radiation directly acts on the surface of a solid body in air or other gaseous medium [10][11][12][13].…”

A methodology, technique, and research results for the synthesis of films on a glass surface upon irradiation of aqueous solutions of copper sulfate with laser radiation are presented. The studies used the radiation of a yttrium-aluminum garnet laser, its second harmonic and the radiation of a semiconductor laser. Solutions with different concentrations of copper sulfate were used. The structure and and characteristics of the control films obtained as a result of drying solutions without exposure to laser radiation. Films synthesized under the action of laser optical characteristics of the films obtained in this case are compared with the structure radiation have both ordered and disordered structures. The characteristic dimensions of the structural elements of these films are 0.5-2 microns. For solutions with low concentrations, the density of the coating of glass substrates with films obtained under the action of laser radiation is much higher than the density of the coating with control films. The transmissions of the films were studied in the spectral range 300-1200 nm. It was found that the transmission of films obtained under the action of laser radiation and control films differ.
