Abstract

The invention relates to a preparation method of germanium tellurite glass optical prefabricated rod output by green ray, a component formula of the glass and a preparation method. The glass material has strong up-conversion green ray luminous intensity. When the luminous strength of the green ray is the greatest, the mixture ratio of the glass is as follows: 55mol% of TeO2, 3.75mol% of GeO2, 12mol% of ZnO, 50mol% of ZnCl2, 0.75mol% of Er2O3, and 3.5mol% of Yb2O3. The oxychloride tellurite glass prepared by the melting method is transparent, has favorable devitrification resistance capability, and excellent physical or chemical property; After the oxychloride tellurite glass with different contents of ZnCl2 is pumped by utilizing a semiconductor light source in a waveband of 980nm, the up-conversion green ray luminous intensity of the glass is dramatically improved. The glass can be applied to the up-conversion fibre optical laser and the color display device output by green ray.

Description

technical field [0001] The invention relates to an oxychlorotellurate glass and a preparation method thereof. In particular, it relates to a method for preparing a germanium tellurite glass optical fiber preform with green light output. Background technique [0002] How to obtain low-cost, high-efficiency, small-scale and high-power output short-wavelength lasers such as blue-green light is the focus and difficulty in the field of optoelectronic functional materials and optoelectronic devices. This is mainly due to its application in optical information processing technology, video display, laser printing , laser medicine and surface treatment and other aspects of a wide range of applications. For example, in underwater transmission, it can solve the saturation problem (Jelov minimum) that electromagnetic radiation transmission can only work in the low frequency (100Hz) region and 400-500nm region, and realize the deep and fast transmission of submarine signals; in biomedic...
