Abstract
In this project a technique to optically measure the temperature is evaluated. The measurement is to be performed through optical fibres during photodynamic laser treatments or laser thermo therapy of malignant tumours. For this technique Cr<sup>3+</sup>-doped crystals were used. The lifetime of the ions' fluorescence were measured, since the fluorescence is strongly temperature dependent. A piece of a crystal was attached to the tip of an optical fibre. The crystal was excited at 635 nm, which is the wavelength most frequently used for photodynamic treatment. An accuracy in the temperature measurement of
