Abstract

Various types of pulsed lasers such as the excimer laser have been used in the ablation of tissue. The study introduced in this note aims to investigate whether the excimer laser induced bubble also derives from vaporized water. As such, the threshold radiant exposure for bubble formation at a bare fiber tip was compared to that of two types of excimer lasers. An absorber was added to the water to induce bubble formation. The results indicate that laser induced bubble is predominantly water vapor. In both mid-infrared lasers and ultraviolet lasers, the vaporization of water is a conceal event for tissue ablation.
