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 a zinc oxide component that can adjust the glass viscosity into the multi-component phosphate glass system. Low-threshold fluorine-containing phosphate fundamental frequency laser color separation glass material. The preparation method is as follows: a phosphate basic glass system is composed of alkali metal oxides, alkaline earth metal oxides, aluminum oxide and phosphorus pentoxide, and the ultraviolet absorption edge of the glass is blue-shifted and improved by introducing rare earth fluoride components. Its glass-forming performance, introducing zinc oxide to adjust the viscosity and forming performance of the glass; the crucible is covered and sealed, and H is introduced into the crucible during the high-temperature clarification process of the g...

[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 in turn, heat and melt through a silicon carbide electric melting furnace, control the melting temperature at about 1250°C, and the melting time is 6-8 hours. The liquid is stirred. The crucible is covered and sealed, and H is introduced into the crucible during the high-temperature clarification process of the glass liquid. 2 or H 2 The mixed gas with Ar gas creates a reducing atmosphere, controls the valence state of fundamental frequency absorption 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 320°C through the leakage noz...

Abstract

The invention belongs to the technical field of laser glass material, and more specifically relates to a low-fluorine phosphate fundamental frequency laser color separation glass, and a preparation method thereof. The low-fluorine phosphate fundamental frequency laser color separation glass comprises, by molar mass fraction, 1 to 10% of Li2O, 0 to 8% of Na2O, 2 to 15% of K2O, 2 to 10% of MgO,0 to 5% of CaO, 0 to 2% of SrO, 1 to 6% of BaO, 1 to 9% of Al2O3, 1 to 10% of ZnO, 55 to 75% of P2O5, 0.1 to 3% of YF3, 0.1 to 2.5% of LaF3, 0.5 to 3% of FeO. The preparation method is capable of solving problems of fluoride glass and high-fluorine glass systems that crystallization is easily caused, glass formation tendency is poor, volatilization is high, homogenization and strip eliminating are difficult to realize, and large size moulding is difficult to realize because of low viscosity; under equal testing conditions, laser damage threshold value of the low-fluorine phosphate fundamental frequency laser color separation glass is obviously higher than that of fused-silica glass materials; and the low-fluorine phosphate fundamental frequency laser color separation glass can be used for replacing fused-silica glass in high-energy high-power lasers to increase laser loading capacity of systems.

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 fundamental frequency laser color separation glass and a preparation method thereof. Background technique [0002] Using deuterium and tritium that can be extracted from seawater as fusion fuel, laser-driven inertial confinement fusion (ICF) technology, which produces high-gain fusion energy by controlled nuclear fusion under strong laser confinement, is recognized as the most important technology in the 21st century. The dawn of clean new energy, and laser-driven inertial confinement fusion technology 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, whi...
