Abstract
A linear relationship is found between the34S isotopic enrichment factor per pulse and the focal distance of the lens used to concentrate the laser beam. From this, one derives a threshold power of 26 MW/cm2 for photodissociation, a mean absorption of 100 photons of 10.59 μm wavelength per32SF6 dissociation, and a dependence of the enrichment factor on the 3/2 power of the laser pulse energy.
