Abstract

The procedures suggested in the standardization draft ISO/CD 11146 for measurement for beam widths and beam radii are tested critically in application to several laser systems common in industrial use. It is shown from measured intensity profiles that the above mentioned procedures require data filtering and introduction of a cutoff. Examples of filtering and cutoff are given. The influence of filtering and cutoff on the results is shown. The use of the presented additional data processing is demonstrated in several measured examples. A slight modification of the definition of beam parameters is invented and a fitting routine for their calculation is specified. Application to beams of typical stable and unstable resonator systems as well as coaxial resonator systems is presented. The results of the paper recommend a supplement of the standardization draft.
