摘要
The present invention provides a cesium-rubidium-borate nonlinear optical crystal, which is represented by the chemical formula CsxRb1-xB3O5 (0x1), and belongs to the P212121 space group with the unit cell parameters in the following range: a=8.202-8.514 Å, b=10.075-9.140 Å, c=5.375-6.207 Å and Z=4. A preparation method of the crystal is as follows: a cesium salt, a rubidium salt and a boron-containing compound are mixed pro rata, heated, kept at a temperature, and then cooled down to obtain the cesium-rubidium-borate. The cesium-rubidium-borate and a flux are mixed and heated to form a melt to obtain a mixing melt. Then a seed crystal attached to a seed rod is dipped into the mixing melt and the seed rod is rotated simultaneously. The melt is kept at 620-780° C., and then cooled down slowly at a rate of 0-5° C. per day. The obtained crystal is drawn out of the melt surface and cooled down to room temperature. Thereby, the cesium-rubidium-borate nonlinear optical crystal is obtained. The crystal can be used for laser light wavelength conversion, optical parametric amplification, electrooptic modulation, optical waveguide and etc.
