Paper Abstract

The spatial and temporal characteristics of the laser beam extracted from the industrial high power cw CO2 laser are investigated experimentally and analysed. The beam properties are compared for two optical stable cavity configurations characterised by the different values of the Fresnel number. It is found that the beam shape fluctuations, observed for both cavities, are mainly due to the mechanical vibrations of the laser construction. The cavity of the lower Fresnel number emits the beam ofbetter quality and provides better focussing condition in the processing zone.
