Paper Abstract

An increasing number of industries, to include military, medicinal, and technological arenas, are using 1.3 micron laser systems for which current skin and eye guidelines are identical. No skin threshold, ED50 or exposure data are available. The mechanisms of laser-tissue interaction with skin at 1.3 microns are unknown. Together, these facts necessitate increased research to prevent future laser accidents and injuries. This study examines the method of interaction of 1.3 microns laser light with tissue in the Yorkshire pig. Our research addresses laser-tissue interaction through delivery using a Nd:YAG with an intracavity filter producing 1.3 micron light at 0.5 millisecond exposure time and in the range of 137 to 475 J/cm2. Laser exposure to Yorkshire pigs was evaluated for dermal lesion development. Lesions were appraised for acute, one-hour and 24-hour post exposure presentation.
