Laser glass containing silver nanoparticles and its manufacturing method

Abstract

The invention provides a laser glass containing silver nanoparticles, the components of the laser glass containing silver nanoparticles are represented by mole percentage, and the cation contains: P 5+ : 50~70%; Al 3+ : 10~20%; Sb 3+ +B 3+ : 5~10%; Nd 3+ : 0.5~2%; Mg 2+ +Ca 2+ +Zn 2+ +Sr 2+ +Ba 2+ : 10~20%; Ag + : 1~5%; Na + +K + : Greater than 0 but less than or equal to 2.5%. The silver-containing nanoparticle laser glass obtained by the invention has a large stimulated emission cross section, and is suitable for repetition frequency devices and high-power continuous laser emitters.

Description

technical field [0001] The invention relates to a laser glass, in particular to a silver-containing nanoparticle laser glass and a manufacturing method thereof. Background technique [0002] Laser glass is a glass that can output laser light under the condition of specific external energy supply. It has a wide range of applications in large scientific installations, land-based / aerospace target protection and other fields. A lot of work has been done to optimize the optical properties required by laser glass from the perspective of glass composition design, such as nonlinear refractive index, stimulated emission cross section, thermo-optic effect, photoelastic coefficient, etc. For example, CN105753316A discloses a laser neodymium glass that eliminates the thermo-optic effect, CN109081579A discloses a laser neodymium glass with a relatively small photoelastic coefficient, and CN101973706A discloses a laser glass doped with ytterbium fluorophosphate. There is still room for i...
