Abstract: Optical elements having an intrinsic anti-reflective sub-wavelength structure (SWS) built into one or more surfaces thereof so that the structure becomes integral part of the surface of the lens. The SWS is in the form of a structure of identical or similar objects such as straight or graded cones, pillars, pyramids, or other shapes or depressions, where the dimensions of the objects and the distances between them are smaller than the wavelength of light with which they are designed to interact. The SWS can be a periodic or random, and can be the same across the entire surface or can vary across the surface so as to correspond with the index of refraction of the lens at that point.

Abstract: An infrared laser source system that combines laser emitters through an optical waveguide. Each emitter is coupled to a port of the optical waveguide and the waveguided signal is combined to provide a spatially combined laser source with a single common exit aperture. The materials used for waveguiding allow the propagation of wavelengths in the infrared. The system can be used for combining multiple laser emitters to increase the total output power and/or for combination of multiple emitters with different wavelength for increased spectral coverage out of the laser system.

Abstract: Method of Making particles including a YAG core and a coating of sintering aid deposited thereon. The particles and agglomerates thereof maybe formed as a powder. The coated YAG-containing particles are well-suited to production of polycrystalline YAG-containing ceramics. The coated YAG-containing particles may be fabricated using a novel fabrication method which avoids the need for formation of a homogeneous powder mixture of YAG and sintering aid. The mixture may be sprayed into a drying column and dried to produce coated particles. Alternatively, the YAG particles and sintering aid or sintering aid precursor solution may be separately introduced to the drying column and dried to form coated YAG-containing particles.

Abstract: A transparent polycrystalline ceramic having scattering and absorption loss less than 0.2/cm over a region comprising more than 95% of the originally densified shape and a process for fabricating the same by hot pressing. The ceramic can be any suitable ceramic such as yttria (Y2O3) or scandia (Sc2O3) and can have a doping level of from 0 to 20% and a grain size of greater than 30 although the grains can also be smaller than 30 μm. Ceramic nanoparticles can be coated with a sintering aid to minimize direct contact of adjacent ceramic powder particles and then baked at high temperatures to remove impurities from the coated particles. The thus-coated particles can then be densified by hot pressing into the final ceramic product. The invention further provides a transparent polycrystalline ceramic solid-state laser material and a laser using the hot pressed polycrystalline ceramic.
