Highly transparent ceramics on the basis of nanopowders synthesized in laser plume. Part II. Laser ceramics

Abstract

In this work we report on the investigation of characteristics of highly transparent ceramics on the basis of nanopowders synthesized in laser plume. It is shown that this approach enables to increase the "orange peel" formation threshold in the ceramics with strongly disordered crystalline structure. It opens the road to application of oxide materials with such a structure as the gain media with oscillation efficiency higher than 50% and also leads to simplification of the synthesis technology of magnetoactive ceramics and to production of highly transparent YAG samples without the use of sintering heterovalent additives.

X-Ray Induced Light Emission of Yttrium Oxide

“…Its optical properties have been widely studied in terms of its use as a host matrix material for doping with rare earth ions such as samarium, erbium, gadolinium and europium for luminescence applications [see, for example, 4-6]. As for pure yttrium oxide, its optical properties have been less studied, nevertheless, in recent years a number of works has paid attention to its luminescent properties in connection with new possibilities of using as active elements of solid-state lasers [7][8] and luminophores [9].…”
