Er:Yag Laser Tissue Ablation as a Surface Vaporization Process: A Computatinal Modelling Study of Pulse Duration Importance

Abstract
Laser tissue ablation is taking important roles in surgical and medical applications. Therefore, it attained great attention from researchers to continuously enhance its therapeutic outcome. In this paper, Er:YAG laser tissue ablation was investigated using computational model. The model assumed laser tissue ablation a water surface vaporization process. Pulse duration was varied by two order of magnitudes and was found to have significant influence on the ablation outcome. The model predicted the existence of optimum pulse duration value that maximizes ablation rate while minimizes thermal damage. Determination of the exact value of such optimum will be investigated in future works. Keywords - Surface Vaporization, Laser Model, Ablation, Thermal Damage, Pulse Duration
