Paper Abstract

The authors describe the results of recent droplet superheating experiments following excitation by pulsed lasers. Under low-irradiance excitation by either a short-pulse (0.4 microsecond(s) ec) or a long pulse (10 microsecond(s) ec) CO2 laser, two superheating thresholds may be identified, the deformation and disintegration thresholds. For higher-irradiance excitation by a Nd:YAG laser (pulse length approximately 10 nsec), the authors report observation of an evaporative instability in laser-irradiated microdroplets. The threshold behavior of these phenomena is discussed and a qualitative description of the effects is given.
