Beta-Barium Borate (β-BaB2O4 or BBO) is a kind of nonlinear crystal with good performance. It can be widely used in dye laser, ultrafast pulse laser, titanium sapphire, argon ion laser, copper vapor laser and other different types of laser systems. In addition, the OPO and OPA systems of BBO crystal can be used to generate a large range of adjustable phase dry light radiation from ultraviolet to infrared.
