Paper Abstract

A general simple experimental technique is given which allows the determination of the parameters characterizing the free propagation of a high power laser beam. The verification has been done with a 5 kW CO2 industrial laser operating in its two possible stable configuration modes. The dependance of beam characteristics on laser power has been also investigated. The beam size was found to decrease with increased rated power while the waist moved consistently: this has been mainly attributed to the output window thermal distortion. The number of peaks in the intensity distribution along the direction of maximum diameter, was not altered, but the geometry of the best beam envelope varied with power.
