Paper Abstract

A numerical simulation of the micro-explosion process during hard tissue ablation with infrared laser has been developed. This simulation investigates the explosion dynamics evolution of the water film in the Er:YAG and CO2 laser irradiation and calculates the pressure and intensity of impulse on the hard tissue surface. The calculation results indicate that the micro-explosion has its special duration for different parameters. The pressure on the target surface caused by the explosion increases rapidly with the laser intensity increase and the maximal pressure value appeared for an adaptive water film thickness.
