Paper Abstract

Calculi fragmentation experiments were conducted in vitro by using Er:YAG laser light. The laser light delivery system was composed of a cyclic olefin polymer (COP)-coated silver (Ag) hollow fiber and a quartz cap to seal the output end of the hollow fiber. Sealing-caps wiht various distal end goemetries were fabricated and the focusing effects for Er:YAG laser light were measured both in air and in water. Fragmentation characteristics of the sealing-caps were investigated. The deterioration of sealing-caps after calculus fragmentation was also experimentally discussed.
