Abstract
ISO-DIS 11254 specifies a test method for determining the laser radiation induced damage threshold of optical surfaces. It has been the intention to provide a method for obtaining consistent measurement results which may be rapidly and accurately compared between different testing laboratories. Measurements according to ISO-DIS 11254 were performed with a Nd:YAG-laser with 15 ns pulse duration. Five-hundred-forty-four test sites are included in the determination of the damage probability in dependence of the power density. An extrapolation of the damage probability to zero results in the damage threshold. Critical parts of the experimental set-up like beam diagnostics, beam attenuation, and damage detection are considered in detail. Some shortcomings of the specified testing procedure are discussed on the basis of selected examples.
