2015-6-1 · The crystal consists of BO 3 planar groups that are the origin of the nonlinearity . The transmission range of BBO, which is a negative mono-axial crystal with large birefringence, covers 189 nm−3.5 μm. The pm range for an Nd laser is 0.205−1.50 μm, and it can be used for SHG, THG, and fourth-harmonic generation …
