SBIR Phase I: Hydrothermal Growth of Potassium Beryllium Fluoroborate (KBBF) for deep UV Nonlinear Optical Applications.

这个小型企业创新研究第一阶段项目是开发一种使用水热技术的KBe2BO3F2(KBBF)单晶的商业生长工艺。KBBF作为一种深紫外光非线性光学材料(NLO)显示出优异的应用前景。NLO对于波长低于200 nm的固体激光器的发展至关重要，这些固体激光器用于光刻、微加工和光谱分析。200纳米以下的区域是极其难以进入的，而且这种波长的光学元件相当罕见。商业KBBF的成功开发将使激光在深紫外区的倍频和波长混频等应用成为可能。目前，这种材料在公开市场上是无法获得的。中国投入巨资开发这种材料，但已禁止其出口。

This Small Business Innovative Research Phase I project is to develop a commercial growth process for single crystals of KBe2BO3F2 (KBBF) using hydrothermal techniques. KBBF shows exceptional promise as a deep UV non-linear optical material (NLO). NLOs are vital for the development of solid-state lasers with wavelengths below 200 nm for use in photolithography, micromachining and spectroscopy. The sub-200 nm region is extremely inaccessible and optics for those wavelengths are quite rare. The successful development of commercial KBBF will enable laser applications such as frequency doubling and wavelength mixing in the deep ultraviolet. Currently, this material is unavailable in the open market. China has invested heavily in developing this material but has embargoed its export.
