Lasers and laser-related equipment Test methods for laser beam widths, divergence angles and beam propagation ratios Part 2: General astigmatic beams - First edition
N 11146-2
Annotation
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 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.

Эта часть ISO 11146 определяет методы для измерения ширин луча (диаметр), углы расхождения и отношения распространения луча лазерных лучей. Эта часть ISO 11146 применима к общим астигматическим лучам или неизвестным типам лучей. Для стигматических и простых астигматических лучей ISO 11146-1 применим.
