Abstract
A method for preventing a plume from contaminating a surface of material that has been cut by a laser or focusing optic wherein the laser produces the plume, the method comprises providing a first airflow beneath the plume with the airflow redirecting the plume away from the surface of the material. A second airflow is provided to further lift the plume to an exhaust. Apparatus is configured to direct first and second air flows such that the plume is not deposited on the material being cut by the laser or on the focusing optic.
