The article proposes a new paradigm of the world order based on the principles of compromise and harmony. In place of liberalism, the world of prehistory, there is a true history — the system of sociohumanism. The dyadic paradigm of the "struggle"

The effect of pump nonequilibrium on the heat generation and the parameters of turbulent flow in the active medium of a fast-flow gas-discharge laser is studied. It is shown that the amplitudes of the turbulent pulsations of the density and refractiv

Solid-phase damage of the silicon surface due to the generation and accumulation of dislocations is studied. The dislocations are generated under the pulse-periodic action of a YAG: Nd laser. The number of laser pulses that causes surface damage vs.

Theoretical and experimental investigations showed that a diverging thermal gas lens, which forms in high-power industrial lasers with fast axial flow of the active medium, can influence the diffraction losses in the laser oscillator and the beam par

Emission spectroscopy methods were used in an investigation of thermodynamic parameters of a surface plasma formed by the action of cw CO2 laser radiation of (2–5)×106 W cm-2 intensity on stainless steel in a protective He or Ar atmosphere. The sp

A study is reported of the influence of a laser mixture relaxing outside the discharge zone on the parameters of the radiation emitted by a cw CO2 laser. It is shown that resonant nonlinear absorption of the radiation may appear, in a certain range o

It is shown that, taking into account the hydrodynamic phenomena accompanying the development and maintenance of a deep laser-induced vapor-gas channel in a liquid, it is possible to estimate the order of magnitude of the channel depth and growth rat

A hydrodynamic model is developed to describe the formation of periodic layered structures in heterogeneous condensed systems composed of immiscible components under the action of high-power laser beams in the regime of channeled penetration. The mod

A gasdynamic model is proposed to describe the phase separation in heterogeneous systems of immiscible components under the action of scanning laser pulses in the channeled penetration mode. The model takes into account the motion of immiscible compo

Numerical comparisons of some models for estimating the power losses due to heat conduction in process of gas-assisted laser cutting are presented in this paper. In spite of differences between these models their results match fairly well.
