Lasers and laser-related equipment - Test methods for laser beam widths, divergence angle and beam propagation ratios - Part 2 : general astigmatic beams

ISO 11146-2:2005 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. ISO 11146-2:2005 is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams, ISO 11146-1 is applicable. Within ISO 11146-2:2005, the description of laser beams is accomplished by means of the second order moments of the Wigner distribution rather than physical quantities such as beam widths and divergence angles. However these physical quantities are closely related to the second order moments of the Wigner distribution. In ISO/TR 11146-3, formulae are given to calculate all relevant physical quantities from the measured second order moments.

Lasers and laser-related equipment - Test methods for laser beam widths, divergence angle and beam propagation ratios - Part 1 : stigmatic and simple astigmatic beams

ISO 11146-1:2005 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. ISO 11146-1:2005 is only applicable for stigmatic and simple astigmatic beams. If the type of the beam is unknown and for general astigmatic beams ISO 11146-2 is applicable.
