Paper Abstract

Photographic studies of pulse infrared laser irradiation of a pure-water target illustrate two aspects of mass removal: (1) surface evaporation, and (2) explosive vaporization. A pulsed Erbium:YAG (Er:YAG) laser provided radiation at a 2.9 micrometers wavelength for delivery to the target site and triggered a second visible laser (nitrogen/dye laser) for illumination of the target site for photography. A variable time delay between the Er:YAG and dye lasers allowed selection of the time of the photograph (
