ABSTRACT:
A method and apparatus for the ablation of hard biological material, such hard dental material, using a rapidly pulsed laser employ a crystal disposed in the propagation path of the laser radiation, the crystal being disposed at the laser output and serving as an interface with an optical conductor which conveys the laser radiation to the treatment site. The crystal smooths the time/intensity characteristics of the pulsed laser radiation to the extent that transmission to the treatment site using optical wave guides is possible. Additional protective features are provided to prevent the ablated biological material to destroy the exposed optical end surfaces of the treatment applicator. Additional design features improve the ergonomic efficiency of the handpiece and its ability to be sterilized.
