Visualization of optical gradient-index lens structure defects with refraction index radial distribution Gradient-index lenses, elements of nonlinear optics, refer to the functional materials of optics. Heterogeneity of the gradient-index lens structure leads to a deterioration in optical properties. It is shown how it is possible to reduce the number of defects at the stage of thermal sintering process of the charge frit stock.

Dental implants surface analysis after exposure to radiation of laser dental systems Laser methods are also being actively introduced into modern dentistry. Analysis of the implant microsurface of various systems after exposure to laser irradiation at different wavelengths by the results of scanning electron microscopy showed which medical lasers have the most traumatic impact on the implant surface, and which carry the least damage. This will help to select the mode of medical laser operation.

Generation of a new-type laser radiation for solving knowledge-based applied problems. Part 1 A physical basis for the generation of magnetomultipole (MM) radiation in the wavelength range 250–900 nm in the "set of fields + molecular gas" non-equilibrium system is created. The mechanism of the two-dimensional feedback between the energies of the quadratic Stark effect at the low-frequency electric dipole (starter) and the Zeeman effect at the high-frequency magnetic multipole (working) vibrational-rotational (VR) transitions is substantiated.
