    The temperature alterations in the absorption coefficients of water in cartilage and cornea under laser radiation of an IR Free Electron Laser (PEL) were studied for several wavelengths near 2.9 and 6.1 μm water absorption bands using a pulsed photo-thermal radiometer (PPTR). A computation algorithm has been modified to take into account the real IR absorption spectra of the tissue and the spectral sensitivity of the IR detector used. The IR absorption spectra of cartilage and cornea have been also measured by the FTIR spectrometer. It is shown that the values of absorption obtined ising PPTR differ from that obtained by the spectrometer. The limitation and possible errors of two techniques used for have been discussed.
