Laser plasma deposition of the thin alumunium films in vacuum

Abstract

The threshold of the aluminium target destruction has experimentally been determined. It is 8×106 W/cm2 in our conditions. The irradiation regime of the aluminium target has been found when in erosive laser plasma contains minimal number of the liquid drop phase particles of the target material formed by the hydrodynamical mechanism. The deposition regime of aluminium films is found, on which surface there are no liquid drop phase particles of the target material q=4.89×108 W/cm2.
