α-BBO is a negative uniaxial crystal with large birefringence and broad transparent range from UV (190 nm) to mid-infrared (3500 nm). α-BBO grown by WISOPTIC has very good internal quality, less absorption, high extinction ratio and high UV transmission. α-BBO is widely used in deep UV and high power laser systems as devices of Gran prisms, polarizing beam splitters, compensator and so on.

ẞ-BBO is an excellent nonlinear crystal with combination of a number of unique features: wide transparency region, broad phase-matching range, large nonlinear coefficient, high damage threshold, and excellent optical homogeneity. Therefore, ẞ-BBO provides an attractive solution for various nonlinear optical applications such as OPA, OPCPA, OPO etc.

ẞ-BBO also has advantages of large thermal acceptance bandwidth, high damage threshold and small absorption, thus is very suitable for frequency conversion of high peak or average power laser radiation, e.g. harmonic generation of Nd:YAG, Ti:Sapphire and Alexandrite laser radiation. ẞ-BBO is the best NLO crystal for the fifth harmonic generation of Nd:YAG laser at 213 nm. Good laser beam quality (small divergence, good mode condition, etc.) is the key for ẞ-BBO to obtain high conversion efficiency.
