Abstract
A system for manufacturing an airfoil includes a laser beam and a first fluid column surrounding the laser beam to create a confined laser beam directed at the airfoil. A gas flowing inside the airfoil disrupts the first fluid column inside the airfoil. A method for manufacturing an airfoil includes confining a laser beam inside a first fluid column to create a confined laser beam and directing the confined laser beam at a surface of the airfoil. The method further includes creating a hole through the surface of the airfoil with the confined laser beam, flowing a gas inside the airfoil, and disrupting the first fluid column with the gas flowing inside the airfoil.
