Thermal Blooming and Air Breakdown Interaction for Pulsed High Energy Lasers,

Abstract

An experiment has been performed combining the effects of short-time thermal blooming and air breakdown. The experiments demonstrate that, for the cases investigated, total energy transfer is higher for breakdown with blooming than without. Energy increases up to 50% have been experimentally observed. Breakdown processes are highly sensitive to the thermal blooming structure, and the combination of both effects must be taken into account if optimum energy delivery to the target is to be achieved.
