Infrared Skin Damage Thresholds From 1319-Nm Continous-Wave Laser Exposures, Gavin D. Buffington, Clifton D. Clark
Infrared Skin Damage Thresholds From 1319-Nm Continous-Wave Laser Exposures, Gavin D. Buffington, Clifton D. Clark
Gavin Buffington
A series of experiments were conducted in vivo using Yucatan miniature pigs (Sus scrofa domestica) to determine thermal damage thresholds to the skin from 1319-nm continuous-wave Nd:YAG laser irradiation. Experiments employed exposure durations of 0.25, 1.0, 2.5, and 10 s and beam diameters of ∼0.6 and 1 cm. Thermal imagery data provided a time-dependent surface temperature response from the laser. A damage endpoint of fifty percent probability of a minimally visible effect was used to determine threshold for damage at 1 and 24 h postexposure. Predicted thermal response and damage thresholds are compared with a numerical model of opticalthermal interaction. …
