Optical Concept of Quantum Mechanics
Relaxed Optics (RO) is a branch of physics that was created to describe the processes of interaction of laser radiation from the point of view of relaxation of the primary optical excitations of the medium [1-9]. The need for its creation is due to the development of laser technologies. Roughly speaking, it is a synthesis of solid state radiation physics, physical chemistry, physics of critical phenomena, physical optics and quantum electronics into a single system [1-4].
The main concepts of Relaxed Optics: kinetic-dynamic, electromagnetic and coherent have a complex (cascade) structure. Because of this, the main theories and models of relaxation optics have a cascade (chain) structure. Moreover, the elements of the cascade themselves can belong to different sections of physics, which are included in relaxation optics. The photoeffect model adapted in this way includes photoionization processes and thermodynamic relaxation. Depending on the conditions of light absorption (on stable or unstable centers), these two processes can proceed in different directions or in the same direction [1, 2].
To explain the microscopic nature of the formation of stable donor centers in antimonide and indium arsenide, a cascade model of the step-by-step excitation of the corresponding chemical bonds in the excitation saturation regime was constructed. The calculations were based on the two-dimensional lattice of sphalerite. A phenomenological chain of relaxation times was also constructed. The set of these models allowed explaining the formation processes of laser-induced donor centers in indium antimonite and indium arsenide, including the processes of reabsorption and reradiation [1, 2].
A cascade model of excitation of the corresponding number of coordination numbers was used for silicon and germanium. The basis was the phase diagrams of silicon and germanium. This made it possible to explain the reason for the emergence of hedgehog-like laser-induced structures for these materials. The near-surface enrichment of titanium with a hexagonal phase during laser irradiation was also explained [2].
Cascade processes of a slightly different type lead to the optical breakdown of a substance when it is irradiated with focused pulsed laser radiation. In this case, the following chain of processes takes place: diffraction stratification of focused radiation; generation of optically-induced Cherenkov radiation, whose generating cones are perpendicular to the generating cones of focusing; generation of Cherenkov radiation in each cone; interference of Cherenkov radiation; the interference maxima of the short-wavelength part of Cherenkov radiation correspond to the observed cascade pattern of optical breakdown [8, 9]. Moreover, its geometry depends on the wavelength of laser irradiation.
Methods of RO may be used for creation allotropic phases, including low-dimensionality, of carbon [2]. Moreover, depending on the irradiation conditions, transitions are possible both with a decrease in symmetry (diamond - graphite) and with an increase (graphite-diamond) [2]. Other promising directions of development and applications of RO are also considered [1-9].
