NIF small optics laser damage test specifications

PDF Version Also Available for Download.

Description

The Laser Damage Group is currently conducting tests on small optics samples supplied for initial evaluation of potential NIF suppliers. This document is meant to define the specification of laser-induced damage for small optics and the test methods used to collect the data. A rating system which will be applied for vendor selection is presented. Presented here is the plan for qualification of NIF small optics vendors based on laser damage performance. The raster scan test method was chosen in order to provide for testing of significant areas of the samples. The vendor performance at a given fluence is categorized ... continued below

Description

The Laser Damage Group is currently conducting tests on small optics samples supplied for initial evaluation of potential NIF suppliers. This document is meant to define the specification of laser-induced damage for small optics and the test methods used to collect the data. A rating system which will be applied for vendor selection is presented. Presented here is the plan for qualification of NIF small optics vendors based on laser damage performance. The raster scan test method was chosen in order to provide for testing of significant areas of the samples. The vendor performance at a given fluence is categorized as either ''qualified'', ''probable'', or ''fail'', depending on the level of damage observed. This binning system allows a conservative stance for qualification, while providing some insight into lever of risk associated with a lowering on the specifications. The R: 1 mapping technique is reserved in cases where comparisons, not qualifications are needed. Once suppliers are selected, an less intensive pass/fail test will be instituted for production optics.
