晶体中的光频转换是产生195～400nm 紫外光谱范围内相干光束的有效方法。β-硼酸钡新材料的发现,提供了提高效率和扩展光谱范围的可能性。与目前已知的其他非线性光学晶体相比,β-硼酸钡可以有效地产生196～260nm 的强紫外射束。
The optical frequency conversion in the crystal is an effective method to produce a coherent beam in the ultraviolet spectral range of 195-400 nm. The discovery of new beta-barium borate materials offers the possibility of increasing efficiency and expanding the spectral range. Compared with other nonlinear optical crystals known to date, β-barium borate can effectively produce a strong UV beam with a wavelength of 196-260 nm.
