Abstract—

This paper examines methods for the fabrication of optical fluoride nanoceramics and the compaction behavior of precursor powders. We discuss the basic drawbacks to the ceramics under consideration from the viewpoint of the physicochemical properties of fluorides. Lasing in ceramics has been demonstrated in the visible (praseodymium) and IR (neodymium, erbium, thulium, and ytterbium) spectral regions. The advantages of optical ceramics include the possibility of preparing large-aperture samples with improved mechanical characteristics and the presence of their own set of defects, including extensive polysynthetic twinning, which leads to the formation of new optical centers.

光学氟化物纳米陶瓷

摘要-

本文研究了光学氟化物纳米陶瓷的制造方法和前体粉末的压实行为。我们从氟化物的物理化学性质的角度讨论了所考虑的陶瓷的基本缺点。陶瓷中的激光已在可见光（镨）和红外（钕、铒、铥和镱）光谱区域中得到证明。光学陶瓷的优点包括可以制备具有改进机械特性的大孔径样品，并且存在其自身的一系列缺陷，包括广泛的多合成孪晶，这会导致新光学中心的形成。
