Abstract

The temperature of the reaction zone is one of the main parameters for the characterisation of the lasertissue- interaction. JR-radiometry, a non-contact temperature measurement method, is used to determine the temperature of the reaction zone. To be able for measuring inside of cavities, especially of hollow organs, we used JR-fibers to guide the temperature radiation to the complex receiver device. During the laser-tissue interaction the JR-radiation field of the reaction zone is focused on an JR-optical fiber made of AgClBr1. The temperature is measured for Nd:YAG laser application with different power densities and compared with a standart thermographic equipment.
