Paper Abstract

Laser-induced damage is a key lifetime limiter for optics in large laser facilities. After tested on a large-aperture high-power laser facility, a damaged fused silica component is disassembled and conditioned to receive damage test on a small-aperture laser. The damage threshold and growth behavior show the corners on the component are less damage resistant. The acid etch on corner has not effectively increased the damage threshold but lowered the damage growth coefficient. A statistic-based model is presented to extrapolate the threshold data in small-aperture test to predict the damage threshold under functional conditions.
