Claim 19:
20. An ablation procedure performed on soft tissue in a client's mouth using a laser device constructed to produce light having a center wavelength in a wavelength range of 2750 nm to 11500 nm, said laser device including a handpiece having a fiber tip through which light is transmitted, said fiber tip having a diameter in a size range of 400 μm to 1200 μm, the handpiece having a nozzle from which a spray comprising water and air is dispensed to cool the soft tissue in the client's mouth while light emitted from the fiber tip of the handpiece is directed toward the soft tissue in the client's mouth, and the laser device including a flow control for varying a rate at which the spray is dispensed from the nozzle, said flow control being adjustable to dispense water from the nozzle up to a maximum water flow rate and to dispense air from the nozzle up to a maximum air flow rate, said procedure comprising:
adjusting the laser device to operate in a free running pulsed mode providing 60 μm bursts at a frequency of at least 50 Hz, and to produce light having an average optical output power in a power range of 1.75 W to 2.25 W; and
adjusting the flow control to dispense water from the nozzle at a water flow rate in a water flow rate range of 10% to 20% of the maximum water flow rate and to dispense air from the nozzle at an initial air flow rate of 20% of the maximum air flow rate.
