Paper Abstract

The presence of defects in optical materials can lead to bulk damage or downstream modulation and subsequent surface damage in high fluence laser systems. An inclusion detection system has been developed by the National Ignition Facility Optics Metrology Group. The system detects small inclusions in optical materials with increased sensitivity and speed over previous methods. The system has detected all known inclusions and defects and has detected previously undetected defects smaller than 5 microns.
