Problems solved by technology

[0006] Keszler et al. (US Patent No.5,677,921) also reported the application of doped Yb:BCBF crystals as laser crystals. The laser crystals also have the performance of nonlinear optical crystals, so they can be used as self-frequency doubling crystals, and as a promotion and derivative Point out the Ba in the matrix 2+ , Ca 2+ Replaced by other divalent metal ions, including Mg 2+ , but did not declare any practical application when the material BMBF is not doped with rare earth elements

Abstract

The invention relates to BaMgBO3F non-linear optical crystal, a preparation method and applications thereof. The crystal has the following cell parameters: a=17.59, b=30.50, c=8.05, alpha=beta=gamma=90, and z=48. Mg2+is coordinated by four Os and two Fs. The solid-solid phase transition temperature is 900+ / -10 DEG C, the low temperature phase has frequency doubling effect, and the ultraviolet or deep-ultraviolet wave band beams are allowed to penetrate. The frequency doubling effect of the high-temperature phase is zero, the decomposing temperature is 1050 DEG C, and the crystal does not generate deliquescence in air, and is not dissolved in the water solution with the pH valve of 2-12 at normal temperature. The method has the following preparation steps of: mixing the BaMgBO3F with a fluxing agent, and heating into a melt body; forming seeds under the temperature of 0.5-5 DEG C above the temperature of the saturation point of the melt body; subsequently, decreasing the temperature to0-1 DEG C below the temperature of the saturation point, and rotating along with decreasing temperature to grow the crystal; separating the melt body when the crystal is grown to the required size, and decreasing to the room temperature to obtain the BaMgBO3F single crystal. The crystal can be used as the frequency doubling crystal in the optical parametric oscillator or the harmonic generator.

Description

technical field [0001] The present invention relates to the field of optoelectronic functional materials, especially the field of inorganic nonlinear optical crystal materials and artificial crystal growth. . Specifically, the chemical formula is BaMgBO 3 The crystal material of F (abbreviated as BMBF) and its growth method and the application of the material as a nonlinear optical crystal. Background technique [0002] The laser is directly produced by the laser, and often only the laser of a specific wavelength can be produced. For example, the wavelength of the Nd:YAG laser is 1064nm, which is an infrared laser. Using the nonlinear optical effect, the frequency of the laser can be doubled or continuously adjusted, so that the wavelength becomes shorter, and even the wavelength can be reduced to below 200nm, that is, visible, ultraviolet, and deep ultraviolet lasers can be obtained. The shorter wavelength of the laser means smaller coherence length and higher single-pho...
