Abstract

Recent theoretical and experimental findings have produced wide ranges of absorption coefficients for melanin in the visible and near-infrared wavelength ranges. These values have been reported for a variety of laser pulse durations, from less than one nanosecond to CW exposures of several seconds. Here we present the findings of non-linear absorption studies in melanin-doped samples in an effort to reconcile bioeffects experiments and theory across a wide variety of irradiance levels. These studies are of particular interest to laser bioeffects in the retina, for which melanin plays a key role in the absorption of laser energy.
