Experimental investigations of acoustic signals generated bg individua
l laser-irradiated water droplets are reported. The dependence of drop
let destruction thresholds on droplet radius and radiative heating rat
e is determined. A theoretical explanation of our experimental results
is provided in terms of a model that includes the processes of drople
t, evaporation and fragmentation in response to intense laser heating.
