Abstract

This paper describes the data of experimental investigation of Cr,Er:YSGG radiation (2.79 micrometers wavelength) influence on hard tissues of teeth. The laser operated in pulse free-running regime with the pulse energy 100 - 600 mJ at a repetition rate 1 - 2 Hz. The crater depths, as function of energy density and number of pulses, have been obtained. The damage thresholds and absorption coefficients for dentin (~0.5 KJ/cm³, ~350 1/cm) and for enamel (~3 KJ/cm³, ~180 1/cm) have been estimated. The variation of free-running pulse duration in the range of 100 - 700 microsecond(s) did not influence the efficiency of teeth-radiation interaction.
