    Abstract

    Damage to laser rods and associated lenses may occur due to self focusing, surface breakdown or bulk damage in the material. The latter may be due to the intrinsic properties of the material or various localized damage sites in the material. Typical damage thresholds will be given for each of the above. The factors which should be taken into account in order to perform meaningful bulk damage measurements will be discussed. A passive test system using a single 10-μs pulse of amplified spontaneous emission with good spatial and temporal uniformity best satisfies these conditions. Results obtained on such a system will be given.
