<title>Comparison of laser wound morphology in skin at different irradiation conditions</title>

Abstract

Under high-intensity laser pulses the morphology and size of the crater induced in biotissue depends both on biotissue properties and on irradiation conditions. The objective ofthis study is to correlate the wound morphology and patterns of microdestruction with the mechanisms of interaction. Along with the regime of superficial layerwise evaporation of tissue induced by CO2 medical, or selective photocoagulation induced by copper vapor lasers, the present work describes the regime of bulk selective damage of coloration centers that are irregularly distributed in the deep ofthe tissue. Photo induced disruption is the mechanism responsible for it.
