Embodiment 1

[0023] Example 1: Series ReBa 3 B 9 o 18 (Re is a rare earth element other than La and Ce) laser glass preparation method

[0024] Will Re 2 o 3 , BaCO 3 and H 3 BO 3 Mix evenly in a molar ratio of 1:3:9.1 (Re is a rare earth element other than La and Ce); in the muffle furnace, the mixed raw materials are sintered at 800°C-900°C for multiple times, that is: the first time After sintering, take it out, grind it evenly again, and sinter it again, repeat this several times to get ReBa 3 B 9 o 18 (Re is the pure material of rare earth elements other than La and Ce); melt the synthesized pure material in a crucible at a melting temperature of 1000°C-1100°C, and raise the temperature of the melt to 30-50°C above the melting temperature and keep it warm , after the melt is fully melted, it returns to the melting temperature of the melt and remains in the melting state; let the melt cool naturally with the furnace, and the series ReBa 3 B 9 o 18 (Re is a rare earth eleme...

Abstract

Serial rare-earth borate laser glass has a chemical formula of ReBa3B9O18 (Re is a rare-earth element except for La and Ce) or Re (1-x) Re'xBa3B9O18 (x is large than zero and smaller than one; Re and Re' are rare-earth elements except for La and Ce), and the two rare-earth elements can be mixed mutually according to needs. The Serial rare-earth borate laser glass has simple manufacture process, high optical homogeneity, favorable mechanical and heat conduction performances and lower expansion factor, does not dissolve in water and deliquate, is easy to process, can also satisfy the requirement of any large size and is suitable for making working-laser material.

Description

technical field [0001] The invention relates to the field of laser glass, in particular to a series of borate glasses that can be applied to solid laser working materials, their growth method and application. Background technique [0002] Oxide glass was successfully used in the laser field for the first time in the last century, and is currently receiving widespread attention in the fields of optical communications, up-conversion lasers, luminescence, and nonlinear optics. Among them, borate system glass is a kind of suitable and stable matrix material for rare earth and transition group ion doping, and has the advantages of low synthesis temperature, easy preparation and processing, etc., and has high scientific research and practical value. Therefore, rare earth borate glass has become the focus of people's research day by day. The Crystal Growth Group of the Institute of Physics, Chinese Academy of Sciences reported a series of isomorphic powder-phase borate compounds i...
