Beta-barium borate (BBO) has the following exceptional properties that make it a very important nonlinear crystal.
BBO is grown with the flux method. It is a negative uniaxial crystal, with ordinary refractive-index (no) larger than extraordinary refractive-index (ne).

The Sellmeier equations (λ€in μm):
BBO is of particular importance in the visible and far UV. A wide variety of phase-matching applications are possible, including the following:
BBO has a low susceptibility to the moisture. The user is advised to provide dry conditions for both the use and preservation of BBO.
BBO is relatively soft and therefore requires precautions to protect its polished surfaces.
When angle adjusting is necessary, keep in mind that the acceptance angle of BBO is small
