Automated damage test facilities for materials development and production optic211 quality assurance at Lawrence Livermore National Laboratory

摘要

The Laser Program at LLNL has developed automated facilities for damage testing211u001eoptics up to 1 meter in diameter. The systems were developed to characterize the 211u001estatistical distribution of localized damage performance across large-aperture 211u001eNational Ignition Facility optics. Full aperture testing is a key component of 211u001ethe quality assurance program for several of the optical components. The primary 211u001edamage testing methods used are R:1 mapping and raster scanning. Automation of 211u001ethese test methods was required to meet the optics manufacturing schedule. The 211u001eautomated activities include control and diagnosis of the damage-test laser beam 211u001eas well as detection and characterization of damage events.
