preparation example Construction

[0041] The present invention obtains a new type of large-scale UV-transparent, high-damage glass by introducing a rare earth fluoride component that can improve its UV transmission characteristics and glass-forming properties, and zinc oxide that can adjust the glass viscosity into the multi-component phosphate glass system. Low-threshold fluorine-containing phosphate double-frequency laser color separation glass material. Its preparation method is: mainly composed of alkali metal oxides, alkaline earth metal oxides, aluminum oxide, zinc oxide and phosphorus pentoxide, adding a small amount of rare earth fluoride, controlling the double frequency absorption ion valence state and glass valence through reducing atmosphere Ultraviolet absorption edge, after high temperature melting, clarification and homogenization, the glass blank is prepared by leakage casting method, and then annealed to obtain high damage threshold and low fluorine-containing phosphate laser glass material. S...

Embodiment 1

[0060] Formulation 1 according to Table 1 # Calculate the weight percent of the glass from the molar composition in the glass, then weigh a total of 25Kg of raw materials, and mix them uniformly in the mixing box. Add the prepared powder into a 13-liter crucible one by one, heat and melt through a silicon carbide electric melting furnace, control the melting temperature at about 1280 ° C, and the melting time is 6 to 8 hours. The liquid is stirred. During the high-temperature clarification process of molten glass, H is introduced into the crucible 2 or H 2 with N 2 The mixed gas creates a reducing atmosphere, controls the valence state of absorbed ions, and reduces the ultraviolet absorption caused by impurity ions. After the glass liquid has been clarified to remove air bubbles and fully stirred evenly, the high-temperature glass liquid is injected into the copper mold preheated to 300°C through the leak nozzle at the bottom of the crucible to form a glass blank, and the ...

Abstract

The invention belongs to the technical field of laser glass materials, and particular relates to low-fluorine phosphate frequency-doubled laser color separation glass and a preparation method thereof. The low-fluorine phosphate frequency-doubled laser color separation glass comprises, by mol mass, 1.5-10% of Li2O, 0.8% of Na2O, 0-15% of K2O, 1.5-10% of MgO, 0-5% of CaO, 0.2% of SrO, 1-6% of BaO, 1-9% of Al2O3, 2-10% of ZnO, 55-75% of P2O5, 1-2% of YF3, 0.5-2% of LaF3 and 0.1-2% of Co3O4. The low-fluorine phosphate frequency-doubled laser color separation glass has the advantages that the problems that fluoride glass and a high-fluorine glass system are prone to devitrification, poor in glass formation tendency, high in volatilization, difficult for producers to remove strips uniformly, difficult to shape in large-size glass due to low viscosity and the like are solved; under the same testing conditions, the laser-damaged threshold value of the low-fluorine phosphate frequency-doubled laser color separation glass is remarkably larger than that of a fused quartz glass material, so that the low-fluorine phosphate frequency-doubled laser color separation glass can be used to replace the fused quartz glass material and applied to a high-energy superpower laser to improve the laser loading capability of a system.

Description

technical field [0001] The invention belongs to the technical field of laser glass materials, and in particular relates to a low-fluorine-containing phosphate double frequency laser color separation glass and a preparation method thereof. Background technique [0002] Laser-driven inertial confinement fusion (Inertial confinement fusion, ICF) uses deuterium and tritium that can be extracted from seawater as fusion fuel, and performs controlled nuclear fusion under strong laser confinement to generate high-gain fusion energy, which is recognized as a clean new energy source in the 21st century At the same time, it is of great significance to promote the research of strong field physics and the development of high power laser technology. In 2014, the National Ignition Facility (NIF) used for ICF research in the United States realized the positive gain output of the laser confinement nuclear fusion experiment for the first time, making human beings take another step towards the...
