Synthesis of Surface Structures at Laser-Stimulated Evaporation of a Copper Sulfate Solution in Distilled Water

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
