    Formation features of run-away electron preionized diffuse discharge (REP DD) and REP DD properties in different experimental conditions are studied. It was shown that sufficient uniformity of REP DD allows its application as an excitation source of lasers on different gas mixtures at elevated pressure. Promising results of REP DD application for development of gas lasers are shown. Stimulated radiation in the IR, visible and UV spectral ranges was obtained in the diffuse discharge. Ultimate efficiency of non-chain HF(DF) chemical and nitrogen lasers on mixtures of SF6 with H2(D2) and N2 was achieved. New operation mode of nitrogen laser is demonstrated under REP DD excitation. Kinetic model of the REP DD in mixtures of nitrogen with SF6 is developed allowing to predict the radiation parameters of nitrogen laser at Ξ» = 337,1 nm. Long-pulse operation of rare gas halide lasers was achieved. Β© (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    It was shown that run-away electron preionized volume (diffuse) discharge (REP DD) can be used as an excitation source of active gas mixtures at elevated pressures and can produce laser emission. We report experimental and calculated results of application of the REP DD for excitation of different active gas mixtures. It was shown that the REP DD allows to obtain efficient lasing stimulated radiation in the IR, visible and UV spectral ranges. Kinetic model of the REP DD in mixtures of nitrogen with SF6 is developed allowing to predict the radiation parameters of nitrogen laser at 337.1 nm. Promising prospects of REP DD employment for exciting a series of gas lasers was demonstrated. Lasing was obtained on molecules N2, HF, and DF with the efficiency close to the limiting value. It was established that the REP DD is most efficient for pumping lasers with the mixtures comprising electro-negative gases.

    The article discusses conditionality desire of students to self-development and the formation of competence readiness in this area of knowledge in classes of P.E. Designed levels determination of formation of readiness for self-development of students of the university. The system contributes to self-realization of the personality of students, formation of physical culture and sports competences and the competence of self-development. The fact is that the current situation in the development of the society and the analysis of the world's sociocultural and educational trends indicate that in recent years, various aspects of the individual's behavior towards his health have become the object of intense public attention and the subject of interdisciplinary research in many highly developed countries under the slogan: "Health is not everything, but everything without health is nothing". Hence the tasks of the student's personality self-development during the intensive preparation for professional activity at the university are aimed at maintaining their own health and improving their physical fitness, considering formation of professional motor skills for effective mastering the future profession and career growth after graduation.peer-reviewe

    It was shown that run-away electron preionized volume (diffuse) discharge (REP DD) can be used as an excitation source of gas mixtures at elevated pressures and can produce laser emission. We report experimental and simulated results of application of the REP DD for excitation of different active gas mixtures. Kinetic model of the REP DD in mixtures of nitrogen with SF6 is developed allowing predicting the radiation parameters of nitrogen laser at 337.1 nm. Peculiarities of the REP DD development in different gas mixtures are studied, as well. It was shown that the REP DD allows obtaining efficient lasing stimulated radiation in the IR, visible and UV spectral ranges. New operation mode of nitrogen laser is demonstrated under REP DD excitation. Laser action on N2, HF, and DF molecules was obtained with the efficiency close to the limiting value.
