Lasers and laser-related equipment. Test methods for laser beam widths, divergence angles and beam propagation ratios - Intrinsic and geometrical laser beam classification, propagation and details of test methods Ingestion-build-1830981 Scope This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams in support of ISO 11146 1. It provides the theoretical description of laser beam characterization based on the second order moments of the Wigner distribution, including geometrical and intrinsic beam characterization, and offers important details for proper background subtraction methods recommendable for
