This paper presents a modification of the Foucault method for measuring the radiation divergence of high-power CW lasers in which the limiting diaphram is produced by an aperture burned through by the laser radiation itself. The method is suitable for beams with any cross-sectional intensitiy distribution. Results of divergence measurements of a CO/sub 2/ production laser with power to 2 kW are presented.
