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