我们考虑了腔增强二次谐波产生384 nm紫外辐射。将新开发的BIBO（BiB3O6）晶体与相同物理形状的LBO（LiB3O5）晶体进行比较。我们发现BIBO的非线性是LBO的九倍，并且它们具有相似的被动损耗。使用BIBO，我们在仅130 mW的耦合IR功率下获得了50%的内部IR到UV转换效率。不幸的是，不稳定的BIBO晶体诱导的IR腔场使CW操作困难，除了低IR功率。
We consider generation of 384 nm UV radiation by cavity enhanced second harmonic generation. The newly developed BIBO (BiB3O6) crystal is compared to a LBO (LiB3O5) crystal of the same physical shape. We find that the nonlinearity of BIBO is nine times larger than for LBO and they have similar passive losses. With BIBO, we obtain an internal IR to UV conversion efficiency of 50% at just 130 mW of coupled IR power. Unfortunately, instability in the BIBO crystal induced by the IR cavity field makes cw operation difficult except for low IR power.
