When a optical fiber is installed and fixed in the capillary filled with water and then Ho:YAG laser is irradiated, water near the tip of the fiber that absorbs the laser energy instantaneously boils, expands and becomes air bubbles. Finally, air bubbles group is induced at the outside of the capillary. The outbreak principle of this induced air bubbles and the process from the outbreak of air bubbles to collapse is visualized in detail. Furthermore, induced air bubbles are acted on the PVA hydrogel that simulated biotissue and the most suitable condition is considered from the behavior and the cutting depth.英語フィールド
