ABSTRACT
Excimer laser machines generate the ultraviolet Argon-Fluoride 193-nm laser and provide for its optical manipulation, computerized control, and final delivery to the cornea. In order to understand the laser machines, one should understand the fundamental concepts of the excimer laser. The word LASER stands for “Light Amplification by Stimulated Emission of Radiation”. The word “excimer” comes from “excited dimer”.
