Components and Packaging for Laser Systems VI.
Successful commerce of science and technology requires standardization of measurement. Today more than ever, there is need for a new Optical Laser Damage standard to increase the efficiency of commerce in the optical industry. The current Laser Damag

Laser-induced Damage in Optical Materials 2019.
In previous years, this committee reported on the need for a US National Laser damage standard, addressing the needs of domestic industry. In 2017, a process was reported that connected the measurement of the active defect density in a small area, a,

Laser-based Micro- and Nanoprocessing XII.
Current fused silica surface processing, aimed at reducing known absorbing precursor concentration, has brought laboratory-tested ultraviolet laser-induced damage rates to nearly nil at fluences up to 10 J/cm2 . Yet this damage rate reduction has not

Laser-Induced Damage in Optical Materials 2017.
This paper reports on the fundamental idea behind a US National Committee, The Optics and Electro-Optics Standards Council (OEOSC) Task Force (TF) 7, proposal for a so-called Type 1 laser damage test procedure. A Type 1 test is designed to give a sim

Optical Interference Coatings 2016.
Dip coating is used to apply sol-gel anti-reflective coatings to large optics for the National Ignition Facility (NIF). Recent process improvements in tooling and Quality Control have enabled production of coatings with improved damaged resistance.

The effect of various HF-based etching processes on the laser damage resistance of scratched fused silica surfaces has been investigated. Conventionally polished and subsequently scratched fused silica plates were treated by submerging in various HF-

For pulse lengths between 1 and 60 ps, laser-induced modifications of optical materials undergo a transition from mechanisms intrinsic to the materials to defect-dominated mechanisms. Elucidating the location, size, and identity of these defects will

Precise assessment of the high fluence performance of pulse compressor gratings is necessary to determine the safe operational limits of short-pulse high energy lasers. We have measured the picosecond laser damage behavior of multilayer dielectric (M

Solid−solid−liquid transitions of DKDP were studied as a function of temperature along the 0.7 GPa isobar. Raman spectra of DKDP were collected at incrementally higher temperatures up to the melting transition. At higher temperatures, the PO4 sym

Local temporal shot-to-shot variation of a high-energy laser system is measured in order to model the maximum fluence that any location on the optic will be exposed to after N shots (Max-of-N). We constructed a model to derive an equivalent-Max-of-N
