Paper Abstract

In this work we represent the results of emission spectral analysis at laser atomization of hard tooth tissues. The spatial-temporal characteristics of laser emission plume for enamel and dentin have been studied. The dynamics of spectrum temporal evolution for enamel and dentin and the spectra in several parts of plume have been evaluated. The analysis of spectrum at transition from high energy sub-msec pulses with comparatively small power density to short sub-nsec pulses with low energy but high power density was carried out. The spectral of emission plume have been investigated under the excitation of laser radiation with several wavelength. The influence of water irrigation on spectrum character was also investigated. It was shown that the spectra character are different for the enamel and dentin at sub-msec duration pulses.
