Problems solved by technology

However, limited by the characteristics of the crystal itself, it is difficult to grow, let alone draw optical fibers, so the nature of the crystal limits the development of optical amplifiers to a large extent
[0004] Although vanadate glass can be made very large and easy to pull optical fibers, traditional vanadate glass is as opaque as a stone. It is a pure black solid with metallic luster and does not have the permeability of visible light. domain use

Embodiment 1

[0012] The mass percentage V of the following main substances in terms of oxides 2 o 5 : 22%; SiO 2 : 28%; Na 2 O: 5%; K 2 O: 10%; Cs 2 O: 5%; CaO: 12%, BaO: 18% Weigh the vanadate glass raw materials and mix them evenly, add them into a platinum crucible and melt at 1400°C for 2 hours under dry oxygen with a concentration of more than 99%. Pouring into shape. Cool in the annealing box from (Tg+10)°C to (Tg-100)°C at a rate of 1°C per hour, then take it out and cool it naturally. After cutting and polishing, the desired transparent vanadate glass can be obtained.

Embodiment 2

[0014] The mass percentage V of the following main substances in terms of oxides 2 o 5 : 31%; SiO 2 : 19%; Na 2 O: 5%; K 2 O: 16%; CaO: 7%, BaO: 11%: SrO: 11% Weigh the vanadate glass raw materials and mix them evenly, then add them to a platinum crucible and melt them at 1400°C under dry oxygen with a concentration of more than 99%. Hours, cast into molds. Cool in the annealing box from (Tg+10)°C to (Tg-100)°C at a rate of 5°C per hour, then take it out and cool it naturally. After cutting and polishing, the desired transparent vanadate glass can be obtained.

Embodiment 3

Abstract

The invention discloses a transparent vanadate glass and method for making same, wherein the glass is based on the conventional vanadate glass V2O5-SiO2, adding alkali metal oxide N2O+K2O+Cs2O and alkali metal hydrate CaO+BaO+SrO. The glass is prepared in environment where oxygen purity is above 99%.

Description

technical field [0001] The invention belongs to the technical field of optical materials, and in particular relates to a transparent vanadate glass. The glass has high transmittance in the visible light region and good optical performance in the infrared region. It can be applied to fiber lasers to promote the realization of physical indicators of super-powerful laser systems in high-energy nuclear fusion simulation experiments, reduce system costs, and improve system efficiency. technical background [0002] Optical fiber is one of the most important technological achievements of mankind in the 20th century, and it has become the basic equipment of the current communication industry. Due to higher efficiency, lower loss and smaller volume, fiber lasers will become the development trend of lasers in the future. [0003] In recent years, the information and communication industry has developed rapidly at an unimaginable speed, and the amount of information transmission has ...
