ER: YAG Laser Tissue Ablation as a Surface Vaporization Process: A Computatinal Modelling Study of Pulse Duration Importance
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.
