Basic peculiarities of modeling the shock processes of Relaxed Optics are discussed. It was shown that these processes may be having nonequilibrium and irreversible nature. Bond between radiated and non-radiated relaxation or processes of Nonlinear and Relaxed Optics is observed. Physical-chemical and electrodynamics’ aspects of these phenomena are analyzed. Modified Rayleygh models and basic theories of Cherenkov radiation are used for the observation of represented experimental data of 4H-SiC. We show that femtosecond laser irradiation may be generated Cherenkov radiation, which is source of further generation of cascade damages in irradiated matter. Comparative analysis the methods of modeling shock waves processes and cascade model of excitation in regime of saturation the excitation are used for modeling the laser-induced breakdown of irradiated matter.

Supramolecular interaction due to the hydrogen bonds formation and their influence on IR - spectra and structure of molecular complexes which is formed due to interaction between carboxylated nanodiamonds and highly toxic drugs on example of doxorubicin and mitoxantrone is analyzed by molecular modeling. As a result of calculations the combined IR spectrum is obtained as imposing of IR spectra for molecular complexes of drugs and nanodiamonds in various interaction positions. Combined IR spectra demonstrates a good agreement with experimental data. Received results demonstrate that there can be strong supramolecular interaction between drugs and modificated detonation nanodiamonds. Formed hydrogen bonds can be considered as one of main mechanisms for targeted drug delivery and for drug retention in cells and, thus, for enhancement of anti-cancer therapeutic efficacy

The article analyzes the indicators obtained in the results of experimental research. These indicators determine physical, chemical, operational and environmental changes as a result of the influence of magnetic fields. A comparative analysis of electrophysical influence on liquid systems was carried out. Calculation of the uncertainty of input values during experimental studies allowed to increase the reliability of decision making regarding the degree of electro-physical impact on ecological indicators.

For the first time calculations have been performed to model evolution of small-angle scattering and diffraction patterns under action of a focused linearly polarized laser beam (650 nm, 25 mW) normally illuminating an AgCl-Ag waveguide film on glass substrate. Calculated patterns obtained for the film thickness of 100 nm are similar to experimental ones both in statics and in dynamics. This is a confirmation of validity of current ideas concerning the mechanism of development of induced diffraction gratings in AgCl-Ag film. Adjustment of grating parameters in the course of modeling, while focusing on the pattern appearance as a whole, provided new information on properties and parameters of the gratings. The main result is a proof of inherent domain nature of the aggregate of gratings. The proposed modeling is a new tool for analysis of experimental results on diffraction grating development in waveguide films.

A difference-frequency generation in the external cavity of a dual-wavelength semiconductor disk laser (SDL) is numerically studied. The dual-wavelength SDL itself has been designed to emit two optical beams simultaneously – the short-wavelength beam (usually referred to as the pump) and the long-wavelength beam (signal). The study is performed with the help of the mathematical model based on a set of ordinary differential equations with a time delay. The model takes into account possible absorption of the pump radiation in the active region designed to provide gain for the signal. The steady state operation point, its stability, and transient dynamics of intra-cavity difference-frequency generator (ICDFG) are analyzed. As the pump radiation absorption exceeds the critical value, the operation point is shown to lose the stability within the certain interval of the primary pomp power. The steady-state instability of the ICDFG develops to the multi-scaled oscillations of high amplitude.

A new construction of the microwave-pumped laser based on the light-pumping cell that uses radiation of sulfur vapor exposed to electromagnetic waves of the microwave band is described. Advantages of this design are the simple structure, high efficiency of the optical pumping cell, the possibility of cooling the pumping element, and easiness of modifying the emission spectrum of the optical pumping by changing the chemical composition of admixtures in the sulfur light-emitting cell. A mathematical tool for the simulation of the short-pulse operation of the microwave-pumped laser is proposed basing on the generalized wave equation solving for a regular transmission line with essentially nonlinear dispersion characteristic and substantial dissipation. Possible techniques for the numerical solving the generalized wave equation are discussed.

The paper suggests synthesis of a VHDL – model of a gas laser installation, efficiently distributing RTL-circuits to create a new list of connections with a minimum set of components. Models of GDC lasers consist of three subtasks: a logic conclusion, optimization received RTL structures and its distribution on structural elements technology mapping.
