Fundamentals of nanotechnology have been created for synthesis of optical ceramics. The technology includes three stages: laser synthesis of nanopowders, static compaction with an ultrasonic effect on nanoparticles, and vacuum sintering. This approach has made it possible to obtain nonporous Nd³⁺:Y₂O₃ and  Nd³⁺:Y₃Al₅O₁₂ laser ceramics of high optical quality.

Two stages of the developed nanotechnology distinguish it from the known technologies. Nanopowders are obtained by laser synthesis method, which provides the smallest nanoparticles (~10 nm) (Fig. 1), and by the pressing of nanopowders by static compaction with ultrasonic treatment of nanoparticles (Fig. 2). This approach facilitates the process of obtaining nonporous highly transparent ceramics, reduces their costs, and opens up the possibility for size increase. The technology is aimed at the creation of active elements of solid-state lasers (Fig. 3) and superpower laser systems.
