Polycrystalline transparent materials are viable replacements for single crystals in a variety of optical applications including solid state lasers, transparent armor, high temperature windows, and scintillators. Further, advantages inherent to ceramic processing may enable new devices and applications that are currently not possible with single crystal materials. This session will focus on processing and properties of transparent polycrystalline materials and the performance of devices that incorporate transparent ceramics. Topics of special interest include novel green forming methods, microstructure control (including grain size, morphology, and texture), sintering and advanced densification methods (microwave, FAST, etc.), optical properties and chemistry of grain boundaries, optical performance, and device performance.
