Abstract

The invention provides a method for vacuum sintering preparation of yttrium aluminium garnet (Y3Al5O12, YAG)-based transparent ceramics under a non-annealing mechanism based on a few Mg single sintering aid system. A small quantity of Mg is taken as a single sintering aid, and a single-step vacuum sintering method is adopted to prepare the YAG transparent ceramics with favorable optical quality and fine grains without later-stage annealing treatment.

Description

technical field

[0001] The invention belongs to the field of advanced ceramic preparation, and relates to a method for preparing YAG-based transparent ceramics with a Mg additive system, in particular to a method for preparing yttrium aluminum garnet (Y 3 Al 5 o 12 , YAG)-based transparent ceramics. Background technique

[0002] With its advantages of high peak power, high efficiency, long life, safety and reliability, solid-state lasers have taken a leading position in the field of laser applications, and are widely used in the fields of national defense, industrial processing, and scientific research. At present, developed countries such as Europe and the United States strongly support the development of solid-state laser technology with the strength of the country. my country has also included it in the "National Medium and Long-Term Science and Technology Development Program (2006-2020)" among the eight cutting-edge technologies. The core component of a solid-state la...
