Abstract

The invention relates to a method for preparing a large chlorine barium borate nonlinear optic crystal and applications thereof. The molecular formula of the crystal is Ba2B5O9Cl. A high-temperature solution method is used, and a fluxing agent is used for cultivating the crystal. The ultraviolet edge of the crystal is less than 230 nm, and the nonlinear optical effect of the crystal is about 6 times higher than that of KDP (KH2PO4). The crystal has the characteristics of good frequency doubling effect, high mechanical strength, easy processing, no deliquescence and the like and has the advantages of rapid preparation, simple operation, low cost, large size and the like. The crystal is suitable for producing nonlinear optical devices and can be widely applied to nonlinear optical devices, such as frequency doubling converters, optical parametric oscillators and the like.

Description

Technical field

[0001] The invention relates to a preparation method and application of a large-size barium chloroborate nonlinear optical crystal, in particular to the nonlinear optical crystal using a high-temperature solution method to grow a large-size crystal. Background technique

[0002] In modern laser technology, the laser wavelength that can be obtained by directly using laser crystals is very limited, and there is still a blank band from the ultraviolet to the infrared spectrum. The all-solid-state blue-green laser system can be realized by generating near-infrared laser from a solid-state laser and then performing frequency conversion through a nonlinear optical crystal. It has important application prospects in various high-tech fields such as laser printing, optical data storage, and full-color display.

[0003] Non-linear optical crystals have attracted much attention because they can effectively broaden the wavelength range of lasers. The main nonlinear optical mat...
