Abstract
In the context of the international EUREKA project CHOCLAB 'Instruments and Standard Test Procedures for Laser Beam and Optic Characterization', it is especially important that work on new standards and test methods for the characterization of laser radiation and optical components should take account of the appropriately standards-oriented measuring technology which will be needed to realize and implement the new standards. The paper presents the latest results of research and development aimed at creating a metrological basis for the characterization of carbon- dioxide laser beams. It describes the current research status of a new, standards-oriented laser beam diagnostics unit capable of determining the power density distribution of the laser beam in the unfocused or focused beam, and based on the hollow needle principle. The paper indicates special features which need to be allowed for when using the moments method for a measuring system and discusses planning for this new measuring system with special reference to automatic measurement of the beam caustic and to the computation and graphic presentation of the beam parameters.
