Abstract
The specific possibilities of the time-resolved fluorescence spectroscopy have been used to determine in on-line measurements the reactive species arising in the reaction zone during laser tissue interaction. The measured radicals, ions and excited atoms are the basic components for the formation of stable harmful chemicals observed in laser plume and therefore the best parameters for the optimization of the laser tissue interaction process. A water aerosol spray system that reduces the emission of the harmful components in the laser plume is described. The effectiveness of this arrangement depends strongly on the water concentration in the interaction zone. The determination of C2, CH and CN radicals which lead to the formation of harmful substances and the OH and O species which characterize the water content of the tissue by laser spectroscopic measurements gives the possibility to optimize the interaction process.
