Abstract
We report the effects of the repetition rate and the beam size on the thres hold for ultrashort laser pulse induced damage in dentin. The observed resu lts are explained as cumulative thermal effects. Our model is consistent wi th the experimental results and explains the dependence of the threshold on repetition rate, beam size, and exposure time. (C) 2000 American Institute of Physics.
