Paper Abstract

We devised a method to continuously measure the distance from fiber tip to stone surface based on the reflectance of an aiming beam back into the fiber during a popcorning scenario to determine how often the stone is close to the laser fiber when firing. Continuous light was coupled into a 200 µm fiber taped immediately next to the holmium fiber. Fibers were placed into a test tube with 5 BegoStones. Reflected light back into the fiber passed through the coupler to a biased photodiode. The fraction of time a stone was within 0.5 mm varied from 5%-18%.
