Abstract

Explosive boiling induced by sub-nanosecond laser pulses  is  theoretically  analyzed in  the  case  of transparent liquids on metal targets. In this case the variation  of boiling  start  times  due  to inhomogeneous  distribution  of  laser  intensity through the  irradiation  spot  can  be  reduced  up  to laser pulse duration and registered explosive boiling pressure signals become less  distorted. The results are  compared with  experimental  investigations  of photoacoustic (PA) signals induced in metal target under  transparent  liquid  layer  irradiated  by  laser pulses of about 100 ps duration and wavelength 532 nm.
