At =0,69 microns the maximal impulsive beam hardness is 60 МW/сm , = 40 nsec. The influence of energy of radiation of arsenic trisulphide by beams with the critical intensities results in photostructural changes. By using a method of Raman spectroscopy the visible changes in the Raman spectra of As S were detected even at laser excitation with =0,78 microns. The maximal changes were detected at illumination by laser with =0,48 microns.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
