ZBYA fluoride glass and preparation method thereof

Abstract

The invention provides ZBYA fluoride glass and a preparation method thereof and belongs to the field of solid laser devices. Near-infrared and intermediate infrared wave-band fluorescent light can begenerated through preparing a Dy<3+> and Tm<3+> co-doped ZBYA fluoride glass matrix; the mol percent of the matrix and co-doping ions meets the following ratio: when Dy<3+> ions are doped, the formulais 50ZrF4-33BaF2-(9-x)YF3-7AlF3-1TmF3-xDyF3; when Tm<3+> ions are doped, the formula is 50ZrF4-33BaF2-(9-x)YF3-7AlF3-1DyF3-xTmF3; and x is equal to 0.2, 0.5, 1, 2 and 3. The ion-doped glass preparedby the invention has high glass transparency and high luminous efficiency and also has good chemical stability; and a preparation technology is simple and the ion-doped glass can be used as a gain medium of a near-infrared and intermediate infrared wave-band optical fiber laser device.

Description

technical field [0001] The invention belongs to the field of solid fiber lasers, and in particular relates to a ZBYA fluoride glass and a preparation method thereof. Background technique [0002] In 1960, mankind obtained the first laser beam for the first time, and the American scientist Maiman et al. designed a chromium-doped ruby ​​fiber output, thus obtaining a laser with a laser beam wavelength of 694nm. Due to the outstanding performance of laser in terms of directionality, coherence and monochromaticity, as well as its high energy and brightness, lasers are quickly applied to many departments such as modern science and technology, national defense technology and national economy. Lasers are used in guidance, processing, Applications in the fields of surgery, controlled thermonuclear reactions, and optical computing have all become internationally attractive technical fields today. Solid-state fiber lasers have attracted much attention due to their small size, high be...

Problems solved by technology

[0006] 2. The composition of the glass is easy to change: the composition and properties of the matrix glass vary widely. Adding different types and quantities of activated ions makes it easier to develop into laser glass with different characteristics;

[0013] 3. The maximum phonon energy of the matrix glass is small

In the mid-1990s, foreign researchers reported that Dy 3+ Mid-infrared fluorescence properties of doped fluorozirconate glasses, due to Dy 3+ The infrared absorption bands of ions at 808nm, 912nm, and nearby are weak, so the pumping efficiency is low when using common commercial near-infrared lasers, and the mid-infrared fluorescence intensity is weak
