A method to modify laser-tissue interactions by microdispensing fluid onto tissues during laser procedures is described. Miniature piezoelectric MicroJets are used to dispense the fluid. Mounted adjacent to laser fiber tips, these jets can dispense individual drops of fluid onto the tissue interactively, between successive laser shots. The fluid drops modify laser impact in various ways. The present paper describes studies in which photoabsorptive fluid (dye) is used to enhance the absorption of the laser energy in dental and in medical orthopedic laser ablation procedures.
