Abstract
The interaction of a 60-fs laser pulse with argon clusters was experimental ly studied. It is shown that cluster heating by an intense femtosecond puls e preceded by a picosecond prepulse can produce plasma whose ionization sta te is determined by the prepulse properties, while the mean energy of hot e lectrons is determined by the main pulse intensity. A simple model of clust er plasma evolution is suggested, allowing an adequate description of its X -ray emission. (C) 2000 MAIK "Nauka/Interperiodica".
