Abstract

The effect of CO2 laser focised radiation (the wavelength of 1O.6,ii't , power density of io 10 VJ/crnt) quartz by method of electron spin resonance (ESR) has been investigated. ESR spectra of crystallic powder (particle size of iO..iOO,M) befor and after laser irradiation at the room temperature have been registrated. Irradia-.. tion of 1O.6,Mlead to appearance of intensive wide asymmetric line ( '& H - 90 iiiT , g '-' 2 , 5 ) and more slight narrow line on the right side of wide line with g=1.943. Appearance of wide line with g2.5 is connected with activisation of paramagnetic centra on the surface of desorienting powder particles. More narrow line with g=1.943 is due to distru.ction of bonds inside of network in region of laser radiation penetration depht.
