Abstract

This paper presents recent results on the experimental testing of characterization methods for laser beam power and energy density distribution as described in draft ISO standards ISO 11146 and 13694. The tests were carried out using various laboratory and industrial laser sources. The accurate and repeatable measurement of distributions is of particular concern. Attention has been paid to background compensation and noise reduction methods. Tests were made to calculate beam uniformity, goodness of fit, beam size and the higher order moments of beam profile data derived from various CCD array detectors. These methods are evaluated in the context of their usefulness for on line monitoring, final laser test, and laser R&D.
