Abstract:
To approximate the absorption of CO2 laser radiant energy by skin and the subsequent distribution of thermal energy in this tissue, the skin was painted with a thin layer of India ink and exposed to ruby laser radiation. The resulting lesions were examined and graded both visually and histologically. The median effective dose for minimal erythema was determined to be 0.8 joulessq cm for an exposure time of 3.5 msec. Histologically measured depth of damage was determined for doses up to 2.8 joulessq cm. It is concluded that the simulated experimental conditions are valid only for doses less than 1.4 joulessq cm.
