Abstract

Time resolved laser spectroscopic measurements have been used to investigate elementary processes responsible for the emitted substances during laser tissue interaction. The results confirm the data obtained with classical analytical methods. CN, OH, CH, and CH₂ radicals were detected during the laser treatment of tissue. It has been found that the original molecules of tissue were reduced into basic compounds from which the emission products were formed. The relative concentration of the radicals depends on the surrounding gas atmosphere (O₂, N₂, He). In the presence of oxygen oxidation processes arise in rivalry with the formation of CN radicals and by this lower the concentration of stable cyano compounds.
