The mechanical response of optical multilayer dielectric (MLD) diffraction gratings has been studied using nanoindentation. The results are interpreted using a stress-strain model, which reveals a uniaxial yield stress of 4.1 GPa. It is shown that th

Chemical-vapor-deposited (CVD) ZnS is an example of a polycrystalline material that is difficult to polish smoothly via the magnetorheological finishing (MRF) technique. When MRF-polished, the internal infrastructure of the material tends to manifest

SummaryIn warmer regions, winegrapes ripen their fruit during the hottest portion of the growing season, producing wines of high pH, low acidity, less intense colour, and a less complex flavour. Experiments were conducted in a commercial vineyard of

During the fabrication of multilayer-dielectric (MLD) thin-film-coated optics, such as the diffraction gratings used in OMEGA EP’s pulse compressors, acid piranha cleaning can lead to the formation of chemically induced delamination defects. We inv

An original procedure and device used for the estimation of a sedimentation constant of magnetorheological fluids have been developed. Experiments that vary the volume concentration and particle size of the dispersed phase, as well as the viscosity o

Magnetorheological finishing (MRF) of polycrystalline, chemical-vapor–deposited (CVD) zinc sulfide (ZnS) and zinc selenide (ZnSe) can leave millimeter-size artifacts on the part surface. These pebble-like features come from the anisotropic mechanic

Liquid crystal polarizers and waveplates are an enabling technology for large fusion lasers. While damage and replacement rates of liquid crystal optics remain remarkably low, degradation in polarizer performance has been noted and studied.
