Abstract
A method for manufacturing an airfoil includes confining an unfocused laser beam inside a first fluid column to create a confined laser beam, directing the confined laser beam at a surface of the airfoil, and penetrating the surface of the airfoil with the confined laser beam. The method further includes detecting penetration of the confined laser beam through the surface of the airfoil via an optical sensor disposed within a cavity defined within the airfoil.
