Paper Abstract

A recurring problem in laser applications is estimating the thermal response of target tissues to laser irradiation. This typically involves using an optical model to determine the distribution of absorbed laser energy and then using a thermal model to establish the temperature during and after laser irradiation. To avoid such modelling and yet allow one to obtain fast, accurate estimates of temperature, a series of charts for laser irradiation of semi-infinite homogeneous media with adiabatic boundaries is presented. These charts were created using analytic solutions of the temperature for absorbing-only media with simple pulsed source geometries. Through the use of nondimensional parameters, these charts allow one to make rapid estimates of the spatial and temporal thermal distributions following laser irradiation for arbitrary pulse durations and absorption coefficients.
