Abstract
Er:YAG laser drilling of dental tissue has been investigated as the ty pical optodynamic process. Optoacoustic signals were detected by micro phone and analyzed within the frame of linear systems theory to monito r laser induced microexplosions. Statistical distribution of the optod ynamic efficiency was performed in terms of partial weights of optoaco ustic response function. The results indicate that the laser spikes sh orter than 2 mu s are more efficient in ablative mechanism.
