Paper Abstract

A novel diagnostic system is presented to measure the two dimensional beam distribution and to calculate the contour line defining the cross sectional area. In order to describe symmetrical as well as asymmetrical beam intensity distributions we define a cross sectional area which 90 % of the beam power containes and which is bounded by a constant beam intensity. This area, or the maximum and minimum diameter of this area are practical parameters for the definition of the beam characteristics. Measurements of focused multi - kilowatt beams are demonstrated. Focus diameters and beam divergences behind the focussing optics are compared for different laser systems.
