It has been experimentally proven that thermal radiation of optically transparent solid objects forms from the entire heated volume within the spectral frequency that is allowed to pass through
The dynamics of the state of spin of the radical oxygen-carbon pair are observed. By way of mathematical modeling, optimal conditions for conducting experiments to obtain the maximum meaningful coefficient of division of carbon isotopes was established
The analysis of the various conditions of the two (four) laser radiation streams coherent addition was realized. It is shown that it is possible to create devices providing continuous subtraction of waves. In such radiation stream a continuous subtraction on the line can be replaced by the continuous addition on the photomultiplier by using a dispersive delay line. The research results can be used for creation of modern open atmospheric connection lines
It is known that transmission coefficient of quartz glass containing the same amount of 28Si and 30Si in the silicon optical fiber is lesser than in commercial LEDs for telecommunications. Therefore it is topical to develop the method of optical glass formation with specified isotope composition in the core and in the shell. The article provides an analysis of physical and chemical processes occurring at the formation of quartz optical fiber blanks by vapor deposition from the gas phase. It is shown that the part of the silicon tetrachloride oxidation stages passes through the radical processes. Therefore for quartz glass formation with specified isotope composition it is possible to use the paramagnetic phenomena caused by the external magnetic field in a high-temperature flow at the quartz glass chemical deposition from the vapor phase. In this case alloy additive using is not necessary. Alloy additives can form density inhomogeneities in the glass. Simultaneous silicon glass formation and silicon isotope separation process bring to significant reduction of the fiber cost in comparison with isotope-enriched materials using. The permanent magnets can be used for magnetic field formation at existing process units
