Abstract

The laws which manage the penetration of a laser beam in tissues have direct connection with the mechanism of biological impact of the laser. The temperature is the main parameter in the interaction between a laser beam and a tissue. In order to predict the thermal reaction in tissues, it is necessary to make a model of the distribution of temperature values within them. Usually, in biological tissues not only one but rather a few thermal effects occur and all of them depend on the parameters of the laser.

Keywords: lasers, biomedical technologies, selective heating of biotissues.
