HGO grows BBO Nonlinear crystals using flux technology. BBO crystal transparency ranges from
188 nm to 5,2 µm, which includes reasonable transparency from
3-5,2 µm for few tens µm thick crystals, while their phase-matchable
range spans almost over the entire transparency range. Combined with other
magnificent properties of BBO, it is favorable for numerous nonlinear
parametric applications. It is worth to mention that BBO crystals have
the highest nonlinearity in the UV range out of all common nonlinear crystals.
