Abstract
To explain the ablation of cortical bone with Ho:YAG-laser radiation a model for tissue ablation at scattering dominated conditions was developed. It states a logarithmic increase of the ablation rate as a function of laser intensity, which is proportional to the penetration depth of diffusion theory. The model considers the increase of the radiant energy fluence rate inside of the scattering medium, which is described by the accumulation factor. Solving an inhomogeneous diffusion equation for the case of isotropic scattering the radiant energy fluence rate was calculated, which delivers an analytical expression for the accumulation factor.
