Abstract: Embodiments of the present disclosure include techniques for forming metasurfaces on optical materials. In one embodiment, light is generated by a light source and coupled through an optical material including a metasurface during an etching process to form the metasurface. Transmission through the optical material and metasurface is performed during the etching process to maximize the transmission of the metasurface. The present disclosure includes apparatuses and method for forming metasurfaces on optical materials.

Abstract: In one embodiment, the present disclosure includes a method of making an optical component. Planes of optical materials are diffusion bonded to make a single larger nonlinear optical device. The bond plane may be configured at an angle to an input wave passing through the diffusion bonded structure. In one embodiment, the optical material is Lithium triborate (LBO). In some embodiments, a plurality of optical materials are diffusion bonded in one or more dimensions to produce a larger optical device. In some embodiments, the larger optical device is used in a laser system. In one embodiment, the present disclosure includes a fusion reactor including a laser system comprising diffusion bonded nonlinear optical materials.

Abstract: Embodiments of the present disclosure include techniques for forming nanotextured surfaces on various materials. In certain embodiments, a nanotextured surface of a wafer is formed in a processing chamber, such as a semiconductor processing chamber. A flat surface opposite the nanotextured surface is attached to a flat surface of a bulk material. In some embodiments the bulk material and the wafer are optical materials. In some embodiments, a second surface of the bulk material is also attached to a wafer having a nanotextured surface and a light may pass through the first nanotextured surface, the bulk optical material, and the second nanotextured surface with low reflection.

Abstract: A non-linear optical crystal, such as a Lithium triborate (LiB3O5 or LBO) crystal, includes a first nanostructured optical surface including distributed pillars and gaps having random heights and cross sections to provide anti-reflection control and scatter control of first light incident on the first structured optical surface. The LBO crystal has an anti-reflective random structured optical surface formed by selective substitution of the surface species Boron-pentoxide (B3O5−) by Lithium Fluoride (LiF), resulting in a depletion layer with low reflectivity and low reflective scatter in the visible, ultraviolet (UV), and near infrared (IR) bands. The LBO crystal with the anti-reflective structured optical surface may be a monolithic structure and thus need not include a coating of an anti-reflective (AR) material, although the LBO crystal may include an optical surface coated by an AR material. The pillars and gaps may be randomly distributed or periodically distributed on the optical surface.
