Lasers and laser-related equipment. Test methods for laser beam widths, divergence angles and beam propagation ratios - General astigmatic beams algolia-search-ignore The results of these tests1 Scope This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This part of ISO 11146 is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams, ISO 11146 1 is applicable. Within this part of ISO 11146, the description of laser beams is accomplished by means of the second order moments of the Wigner distribution
