Abstract

Emission characteristic of laser produced plasma for two pulse lengths of the laser beam at 10.6 micrometers wavelength was studied. Emission lines in Al and Pb plasma were registered in the visible region their time evolution was analyzed and plasma temperature was estimated. A second maximum in intensity of the emissions lines after the laser pulse extinction was put into evidence for short laser pulses as compared with the smooth decay in time of lines for long laser pulses.
