Problems solved by technology

It has a large frequency doubling coefficient, and the ultraviolet absorption edge is around 160nm, but due to the (B 3 o 7 ) 5- The groups are connected to each other, forming a helical chain at 45° to the z-axis in space and cannot be arranged in parallel in the crystal lattice, so that the birefringence of the crystal is too low (Δn=0.04~0.05), so that it can be used in ultraviolet light The phase matching range of the region is severely limited, so that the advantages of wide bandgap cannot be fully utilized

Description

technical field [0001] The invention belongs to the technical field of optoelectronic functional materials, and in particular relates to an alkali metal cyanuric acid monohydrogen salt compound, its crystal, its preparation method and application. Background technique [0002] The nonlinear optical effect of crystal refers to such an effect: when a beam of laser light with a certain polarization direction passes through a nonlinear optical crystal (such as a borate nonlinear optical crystal) in a certain incident direction, the frequency of the beam will be change. [0003] Crystals with nonlinear optical effects are called nonlinear optical crystals. The use of nonlinear optical crystals for laser frequency conversion broadens the range of laser wavelengths and makes the application of lasers more extensive. Especially borate nonlinear optical crystals such as BaB 2 o 4 (BBO), LiB 3 o 5 (LBO), KBe 2 BO 3 f 2 (KBBF), Sr 2 be 2 B 2 o 7 (SBBO), Ba 2 be 2 B 2 o ...
