Abstract

The invention discloses a molybdenum tellurate glass and a preparation method thereof, which belong to the field of optical materials. The composition and ratio of the molybdenum tellurate glass are: 85-15mol% TeO 2 , 5~70mol% MoO 3 , 5~45mol% ZnO. The molybdenum tellurate glass of the present invention has the advantages of a large glass-forming region, excellent thermal stability and mechanical strength, and is an excellent matrix material for near-mid-infrared laser glass optical fibers, which can be applied to the core of fiber lasers and fiber amplifiers gain medium.

Description

technical field [0001] The invention belongs to the field of optical materials, and in particular relates to a novel molybdenum tellurate glass with a large glass-forming area and a preparation method thereof. Background technique [0002] Fiber lasers have broad application prospects in the fields of optical communications, biomedicine, material processing, sensing, nuclear fusion research, and national defense. As the core gain medium of fiber lasers, the exploration of new rare earth-doped laser glass fibers has always been a hot and difficult issue in the field of laser glass. In order to cope with different practical uses, researchers have explored various types of laser glasses. The common laser glass substrates can be divided into two categories, including oxides (including silicate, phosphate, germanate, telluric acid, etc.) salts, etc.) and non-oxide (fluoride and chalcogenide glasses) glasses. Compared with silicate glass, tellurate glass has higher solubility of...
