Abstract
A dental irrigation system is provided with a laser source for generating a laser beam and an optical delivery system for the laser beam. The laser beam wavelength ranges from 0.4 μm to 11.0 μm. The laser system operates in pulsed operation with pulse sets of 2 to 20 individual pulses of temporally limited pulse length. The pulse sets follow one another with temporal separation. The individual pulses follow one another with pulse repetition rate. The laser system generates at least one vapor bubble within the liquid irradiated with the laser beam. A single pulse causes the vapor bubble to oscillate between a maximal and a minimal volume with a bubble oscillation frequency. The pulse repetition rate within one pulse set is adjusted relative to the bubble oscillation frequency such that synchronization between delivery of the pulses and bubble oscillation is achieved.
