Abstract

The invention discloses a preparation method of transparent glass with an intermediate infrared 3.9 mum luminescence characteristic at room temperature. The chemical composition of the glass substrateis (mol%) 26InF3-14ZnF2-19BaF2-11GaF3-8SrF2-12PbF2-5LiF-(4-x)LaF3-xHoF3-1NdF3 (x is equal to 0.2, 0.5, 1, 2, 3, 4, named as xHo-1Nd). The sum of the molar percentages of all the compounds is 100%. The preparation method comprises the following steps of 1) weighing each compound, and stirring and mixing in a mortar, 2) putting the mixture into a platinum crucible, and putting the platinum crucibleinto a 850 DEG C high-temperature furnace for heat preservation for 30 minutes, 3) after the solution glass is cooled, putting the solution glass into a glove box, heating the solution glass for 2 hours at 850 DEG C in an environment full of nitrogen, and pouring the solution glass onto a copper plate preheated at 240 DEG C, and 4) placing the sample in an annealing furnace for annealing treatment to eliminate stress in the glass, and cooling to room temperature after 3 h. The glass prepared by the method has the advantages of high transparency, high luminous efficiency, excellent chemical stability, simple preparation process, and realization of batch production, and can be used as a gain material of an intermediate infrared fiber laser.

Description

technical field [0001] The invention relates to a method for preparing transparent glass with mid-infrared 3.9 μm luminescence characteristics at room temperature. Background technique [0002] With the rapid commercialization of various semiconductor laser light sources, mid-infrared luminescent materials have gradually become one of the current research hotspots. Compared with other types of lasers, fiber lasers have comprehensive advantages such as good diffraction-limited beam quality and compact structure, and have become the mainstream technology in the near-infrared band. Currently, due to the excellent mechanical and thermal properties of silica fibers, Tm 3+ The output power (λ~ 2 μm) of doped silica fiber laser has reached kilowatt level. Due to the large phonon energy (~1100 cm -1 ) and limited infrared transmission range (λ< 2.5 μm), it is impossible to obtain 3-5 μm laser with silica fiber. Fluoride fiber has the advantages of low phonon energy and wide t...
