  abstract = {A theoretical model for calculation of the irradiance distribution along the surface of multimode unclad optical fiber tips used as diffusing tips for photodynamic therapy or scalpels in laser surgery is presented and experimentally verified. The model used is based on modified geometric optics. Good agreement is obtained between the theory and experiment.},
