Abstract
We report a novel method for selective laser energy delivery into biologica l tissues based on refractive-index differences. As a specific example, Ho: YAG laser energy is delivered into fat preferentially over other soft tissu e, despite the fact that water has a higher absorption coefficient at this wavelength than fat.
