Read Abstract +

When discussing laser-induced damage phenomena, the main parameter of interest is the laser-induced damage threshold (LIDT). Since LIDT is a function of irradiation time (or number of pulses), its characterization is of critical importance when designing reliable industrial or medical laser systems or even planning long-term space missions involving high power lasers. Within laser-induced damage community, decrease of LIDT with increase in irradiation time (the so-called fatigue effect) is often estimated by using the S-on-1 test procedure described in the ISO 21254-2 standard. However, due to measurement limitations, S-on-1 tests are usually carried out for relatively small numbers of pulses, therefore additional extrapolation methods must be used in order to predict lifetime of optical components. The simple extrapolation procedure provided by the ISO 21254-2 standard no longer meets the demands of the community as it ignores existence of multiple failure modes and data censoring resulting from different damage detection techniques, therefore a new approach for LIDT extrapolation is much needed. In our previous work [1], we explored application of accelerated lifetime testing (ALT) techniques on S-on-1 test data. ALT approach treats S-on-1 experiments as sets of lifetime (or time to failure) distributions at different fluence levels instead of damage probability curves at different numbers of pulses. We have shown that this approach, combined with Bayesian inference and Markov chain Monte Carlo (MCMC) sampling, is well suited for extrapolation and uncertainty evaluation of S-on-1 experiments. However, proper application of these methods require empirical knowledge about lifetime distributions for different material types and irradiation parameters. Therefore, in this work an attempt is made to experimentally characterize lifetime distributions of highly reflective dielectric and metallic laser optics at both nanosecond and femtosecond pulse durations. UV and IR wavelengths as well as influence of irradiation fluence and polarization state are also considered. The results of this study provided insights into lifetime distributions of laser-induced damage and helped to shape guidelines for extrapolating S-on-1 experiments to longer irradiations. [1] L.

Quality standards are the basis for establishing a common ground between both research institutions and commercial organizations that exchange quantitative information about product features and related issues. In the rapidly changing world, the field of photonics is at the forefront of innovation: research, development, and manufacturing of new types of optics and lasers take place daily. In this context, new important aspects and limitations of the current damage testing approach become apparent. Accordingly, the ISO family of standards (ISO 21254) related to laser-induced damage threshold testing is reviewed and updated regularly. Various inputs into laser-induced damage testing were collected over the years by Lithuanian laser-induced damage community, which is a long-time practitioner of the current and previous revisions of ISO standards. Within this presentation, an attempt is made to contribute to the tremendous work that has already been done. Two types of efforts are made. First of all, we seek to identify weak points, edge cases and areas that leave some space for various misinterpretations and systematic errors. Secondly, we propose possible solutions (with corresponding Monte Carlo simulations for validation) that are currently in practice at laboratories of Lidaris UAB and Laser Research Center of Vilnius University. The suggested inputs are mostly related to definitions of damage criteria, test procedures, analysis of results, selection of appropriate testing protocols and their parameters as well as data representation. By no means, our observations seek to diminish the value of present approaches. As imperfect as they are, current standards were the only appropriate reference for a long time and proved to be adequate in most cases. We believe that the idea of a single protocol that would address all the issues of the community is flawed (considering the wide gamut of optics and lasers), therefore different testing protocols should be viewed as tools to address different problems. We also hope that some of our quantitative inputs could bring more clarity to preconceptions about laser-induced damage testing and significantly improve current approaches.
