This International Standard specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This Part of the standard shall be applied for general astigmatic beams or if the type of the beam is unknown. For stigmatic and simple astigmatic beams ISO 11146-1 can be applied. Within this part of the standard the description of laser beams is accomplished by means of the second order moments of the Wigner distribution rather than physical quantities as beam widths and divergence angles. However these physical quantities are closely related to the second order moments of the Wigner distribution. In Part 3 of this standard formulae are given to calculate all relevant physical quantities from the measured second order moments.
