Abstract

The invention provides a device and method for deoxidizing and purifying infrared arsenic sulfide glass. The device includes a raw material filling pipe, a primary melting tank, an aluminum filling pipe, a purification tank, a forming pipe and a connecting pipe; the preliminary melting tank, the purification tank and the forming pipe are arranged side by side, and the three are communicated with each other through the connecting pipe, thereby forming a M-type structure; the primary melting tank is provided with a raw material filling pipe connected with it; the purification tank is provided with an aluminum filling pipe connected with it. In the present invention, the solid aluminum reacts with the arsenic sulfide glass melt in the form of solid-liquid. On the one hand, aluminum can react with the oxygen impurities in the glass melt, and the oxygen impurities are removed by the subsequent distillation process; On the one hand, in order to avoid the direct contact reaction between the aluminum element and the sulfur element, the present invention utilizes the primary melting tank to realize the preparation of the arsenic sulfide glass melt, and utilizes the purification tank to carry out the oxygen impurity reaction in the aluminum and the chalcogenide glass melt, which can prevent the Aluminum impurities are introduced into arsenic sulfide glass.

Description

technical field [0001] The invention belongs to the field of optical materials, in particular to a device and method for deoxidizing and purifying infrared arsenic sulfide glass. Background technique [0002] Chalcogenide glass has stable thermal properties, high third-order nonlinear coefficient, wide infrared transmission window, and is an excellent infrared optical material. Infrared optical fibers made of chalcogenide glass combine the soft and bendable characteristics of optical fibers, and have important applications in the fields of infrared signal transmission, image transmission and transformation, and mid-infrared fiber lasers. [0003] However, impurity absorption has become a key bottleneck restricting the infrared optical performance of chalcogenide glass fibers. The reason is that due to the existence of impurities such as carbon, hydrogen, and oxygen, chalcogenide glass produces a series of impurity absorption peaks in the mid-infrared band, affecting the The...
