Lasers and laser-related equipment - Determination of laser-induced damage threshold of optical surfaces - Part 3: Assurance of laser power (energy) handling capabilities (ISO 11254-3:2006)

ISO 11254-3:2006 describes a test procedure for assurance of power density (energy density) handling capability of optical surfaces, both coated and uncoated.
ISO 11254-3:2006 specifies this procedure by providing two test methods for assurance of the power density (energy density) handling capability of optical surfaces.
The first method provides a rigorous test that fulfils requirements at a specified confidence level in the knowledge of potential defects.
The second method provides a simple test for an empirically derived test level, allowing an inexpensive test.

Laser und Laseranlagen - Bestimmung der laserinduzierten Zerstörschwelle optischer Oberflächen - Teil 3: Zertifizierung der Belastbarkeit hinsichtlich Laserleistung(-energie) (ISO 11254-3:2006)

Dieser Teil von ISO 11254 beschreibt ein Prüfverfahren für die Zertifizierung der Belastbarkeit hinsichtlich Leistungs¬dichte (Energiedichte) von sowohl beschichteten als auch unbeschichteten optischen Oberflächen.
Dieser Teil von ISO 11254 legt dieses Verfahren fest, indem zwei Prüfverfahren zur Zertifizierung der Leistungsdichte (Energiedichte) angeboten werden.
Das erste Verfahren liefert eine strenge Prüfung, die die Anforderungen bei einem festgelegten Vertrauens¬intervall und bekannten potenziellen Fehlstellen erfüllt.
Das zweite Verfahren bietet eine einfache Prüfung für ein empirisch abgeleitetes Prüfniveau und erlaubt eine kostengünstige Prüfung.

L'ISO 11254-3:2006 décrit un mode opératoire d'essai permettant de vérifier la capacité des surfaces optiques, triatées ou non traitées, à supporter la densité de puissance (la densité d'énergie).
L'ISO 11254-3:2006 spécifie un mode opératoire en présentant deux méthodes d'essai permettant de vérifier la capacité des surfaces optiques à supporter la densité de puissance (la densité d'énergie).
La première méthode présente un essai rigoureux satisfaisant aux exigences à un niveau de confiance spécifié en matière de connaissance des défauts potentiels.
La seconde méthode est un essai simplifié de niveau d'essai dérivé de façon empirique, donc peu coûteux.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11254-3 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 9,
Electro-optical systems.
ISO 11254 consists of the following parts, under the general title Lasers and laser-related equipment —
Determination of laser-induced damage threshold of optical surfaces:
⎯ Part 1: 1-on-1 test
⎯ Part 2: S-on-1 test
⎯ Part 3: Assurance of laser power (energy) handling capabilities

ISO 11254-3:2006(E)
Introduction
Optical components can be damaged by laser irradiation of sufficiently high energy or power density. At any
specified laser irradiation level the probability of laser damage is usually higher for the surface of a component
than for its bulk. Thus the limiting value of an optical component is usually given by the damage threshold of
its surface.
This document provides a test procedure for obtaining consistent measurement results, which may be used
for acceptance tests or may be compared between different testing laboratories.
This testing procedure is applicable to all combinations of different laser wavelength and pulse length
durations. Comparison of laser damage threshold data may be misleading unless the measurements have
been taken at identical wavelengths and pulse lengths.

Assurance of laser power (energy) handling capabilities
SAFETY PRECAUTIONS — Some laser and optical components are made of materials which are toxic
if vaporized (e.g. ZnSe, GaAs, CdTe, ThF , chalcogenides, Be, Cr, Ni). Due care shall be taken not to
damage these materials without taking suitable safety precautions.
