- Abstract
We examine the interaction of short and intense femtosecond laser field with Kr clusters contained ( ∼107atoms). Efficient heating of the cluster by laser is followed by rapid expansion of the cluster and leads to his final explosion. We have used the modified nanoplasma model (by adding tne the term of electron surface collision frequency in the expression of the electron-ion collision frequency) for the study of the interaction of an intense laser field with large Kr clusters, and have found that the hydrodynamic pressure is larger than the coulomb one and the electron energy of electrons after the pulse is passed is found of order of 2.5keV.
