Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios - Part 2: General astigmatic beams (ISO 11146-2:2021)

This document specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This document is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams, ISO 11146‑1 is applicable.
Within this document, 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.

Laser und Laseranlagen - Prüfverfahren für Laserstrahlabmessungen, Divergenzwinkel und Beugungsmaßzahlen - Teil 2: Allgemein astigmatische Strahlen (ISO 11146-2:2021)

Dieses Dokument legt Verfahren zum Messen der Strahlabmessungen (Strahldurchmesser), Divergenzwinkel und Beugungsmaßzahlen von Laserstrahlen fest. Dieses Dokument ist für allgemein astigmatische Strahlen oder Strahlen unbekannter Art anzuwenden. Bei stigmatischen und einfach astigmatischen Strahlen ist ISO 11146 1 anzuwenden.
In diesem Dokument wird die Beschreibung von Laserstrahlen durch die Momente zweiter Ordnung der Wigner-Verteilung gegenüber der Beschreibung durch physikalische Größen wie Strahlabmessungen und Divergenzwinkel bevorzugt. Diese physikalischen Größen stehen jedoch in engem Zusammenhang mit den Momenten zweiter Ordnung der Wigner-Verteilung. In ISO/TR 11146 3 sind Gleichungen zur Berechnung aller relevanten physikalischen Größen aus den Momenten zweiter Ordnung angegeben.

Lasers et équipements associés aux lasers - Méthodes d'essai des largeurs du faisceau, angles de divergence et facteurs de limite de diffraction - Partie 2: Faisceaux astigmatiques généraux (ISO 11146-2:2021)

Le présent document spécifie les méthodes pour le mesurage des largeurs (diamètres) du faisceau, angles de divergence et  facteurs de limite de diffraction. Le présent document s'applique aux faisceaux astigmatiques généraux ou si le type de faisceau est inconnu. Pour les faisceaux stigmatiques et astigmatiques simples, l'ISO 11146-1 s'applique.
Au sein du présent document, la description des faisceaux laser est réalisée au moyen des moments de second ordre de la distribution de Wigner, plutôt que par des grandeurs physiques telles que les largeurs de faisceau et les angles de divergence. Toutefois, ces grandeurs physiques sont étroitement liées aux moments de second ordre de la distribution de Wigner. Dans l'ISO/TR 11146‑3, des formules sont données pour calculer toutes les grandeurs physiques concernées à partir des moments de second ordre mesurés.
