Two-pulse method of laser plasma generation for remote diagnosis

Subject of inquiry: interaction between two-pulse laser radiation and condenced media. The aim of the work is to study effects of increase of analytical parameters of emission spectra of laser plasma when changing single-pulse radiation mode to two-pulse one. Methods of investigation: analytical calculations and physical experiment. A new method of two-pulse laser plasma generation for remote diagnosis has been offered and studied experimentally. A physical mechanism for increase of luminous emittance and contrast of a target spectral lines in atmosphere has been investigated. A magnification of 10 power for sensitivity of the method of remote diagnosis version has been obtained. The field of application of laser remote microanalysis in atmosphere has been essentially widened. A complex of Spectometric equipment has been developed. Field of application: analysis of elements composition, of condensed media according to emissive spectra of laser plasma (Physics Institute of Russian Academy of Sciences, Institute of General Physics of Russian Academy of Sciences, Physics Institute of Byelorussia Academy of Sciences, Kharkov Physics-Engineering Institute, Moscow State University)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
