Abstract

Medical applications of ultraviolet lasers are expected to produce new treatments. We have been doing the basic experiments of UV laser beam biotissue interaction with both KrF and XeCl excimer lasers for more than seven years. However, the optical fiber cannot be used for power UV beams. We have been investigating UV beams. We have tried beam delivery with OH ion-doped quartz fiber and a hollow tube guide. From our experimental results we found the influence of the Cl ions and the formation of defect in the quartz core by two photon absorption.
