Paper Abstract

A new free vortex aerodynamic window, developed for industrial high power CO2-lasers, is presented. To meet the industrial requirements improvements with regard to a reduction of the total nozzle pressure were necessary. The lower pressure results in reduced turbulence and therefore in less influence on the laser beam. This was verified by interferometric measurements as well as by experiments on an industrial laser. Some results of a numerical simulation of the flow in an aerodynamic window aimed at a better understanding of the phenomena involved are presented.
