Paper Abstract

The standardization of laser damage testing is an important prerequisite for development and quality control of optical components exposed to high-power laser beams. The ISO working group ISO/TC 172/SC9/WG6 is currently engaged with the preparation of a standard for laser damage testing. The first part of this standard which is concerned with 1-on-1 damage testing has reached the status of a draft international standard: ISO/DIS 11254-1. To test for the practicability of this characterization method, a round robin experiment was performed within the framework of the EUROLASER-CHOCLAB project. Identical sets of typical Nd:YAG laser components were distributed to the above-mentioned laboratories for LIDT measurements in conformance with the standard. The results are summarized in this paper. Additionally, damage morphologies were examined by microscopic techniques like Nomarksi differential interference contrast and scanning force microscopy.
