BBO is grown with the flux method. It is a negative uniaxial crystal, with ordinary refractive-index (no) larger than extraordinary refractive-index (ne).

SHG phase-matching range from 410 nm to 2100 nm
Transmission from 190 nm to 3500 nm
Large effective nonlinear coefficient
High damage threshold
Wide temperature-bandwidth of about 55°C

The Sellmeier equations ( l in μm ):
n_o²=2.7359+0.01878/(l²-0.01822)-0.01354l²
n_e²=2.3753+0.01224/(l²-0.01667)-0.01516l²

Application:
BBO is of particular importance in the visible and far UV. A wide variety of phase-matching applications are possible, including the following:
Second, third, fourth and fifth harmonic generation of Nd doping lasers.
Frequency-doubling, -tripling and -mixing of Dye lasers.
Second, third and fourth harmonic generation of Ti:Sapphire lasers .
Optical parametric amplifier (OPA) and optical parametric oscillators (OPO).

Note:
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.
