Abstract
Quantification of calculus fragmentation by Er:YAG laser light was experimentally discussed. Er:YAG laser light was delivered to reach a calculus or a model calculus underwater by using a sealed hollow optical fiber. Fragmentation efficiency was obtained for alumina ball used as a model of calculus when sealing caps with various focusing effect were used. Three types of human calculi were analyzed and their absorption properties at the wavelength of Er:YAG laser light were obtained. The relationship among the absorption property, constituents of calculus, and the fragmentation efficiency were also discussed.
