The temperature of the reaction zone is one of the main parameters for the characterization of laser-tissue-interaction. IR-radiometry, a noncontact temperature measurement method, is used to determine the temperature of the reaction zone. To be able to measure the inside of cavities, especially of hollow organs, we used IR-fibers to guide the temperature radiation to the complex receiver device. During the laser-tissue interaction the IR-radiation field of the reaction zone is focused on an IR-optical fiber made of AgClxBr1-x. The temperature is measured for Nd:YAG laser application with different power densities and compared with standard thermographic equipment.
