We describe the cleaning processes, treatment methods, facilities, and cleanliness verification techniques developed to achieve and maintain the demanding cleanliness requirements for both hardware and optics used in the National Ignition Facility (N

High power laser systems require nearly contamination free optics to maintain desired transport efficiency and to minimize optic damage. The required cleanliness is generally achieved through practices that preclude or remove foreign particle contami

In operational laser systems, it is often difficult to keep optical components completely free of foreign material. We have investigated the performance of high damage threshold 1.053 {micro}m high reflectors in the presence of surface contaminants.

A key lesson learned from the earliest optics installed in the National Ignition Facility (NIF) was that the traditional approach for maintaining cleanliness, such as the use of cleanrooms and associated garments and protocols, is inadequate. Assembl

We describe a system to inspect and remove surface debris in-situ from the surfaces of upward-facing mirrors that transport 1053 nm laser light to the target chamber of the National Ignition Facility (NIF) at the Lawrence Livermore National Laborator

The National Ignition Facility will be the highest energy laser in the world when completed. Many small optics (less than or equal to 14" in diameter) have stringent transport efficiency and some have very high laser fluence requirements. For optics
