Abstract :
Research projects on laser heating and ablation and on spectroscopy of biological tissues are described. The discussion focuses on studies regarding microscopic laser light scattering of biological cells and structures, ablation of calcific tissue using pulsed HF laser radiation, and fluorescence and its use in diagnosing atherosclerosis. A specifically designed multifiber laser catheter constructed to collect tissue fluorescence spectra using fiber optics is described.<>
