An overview of laser-tissue interactions is presented in terms of the physical mechanisms of interaction, the time course of tissue response, and the level of biologic structure affected. The factors that affect dosimetry of photodynamic therapy are presented. Laser dosimetry for photothermal and photomechanical interactions is outlined.
