Non-cubic transparent ceramics for laser applications

抄録

In polycrystalline ceramics composed of numerous crystal grains, the development of transparent ceramics, which involves minimizing internal scattering sources, holds significant promise for applications in high-average-power solid-state laser fields. However, in non-cubic materials with birefringence, scattering at grain boundaries occurs, making it difficult to achieve laser-quality transparency. Addressing this issue is expected to propel the development of novel laser materials, sources, and applied technologies. This paper provides an overview of the techniques and current status of non-cubic transparent ceramics and presents the author’s research findings on transparent ceramics composed of nanocrystalline grains.
