BBO (beta-BaB2O4) is a nonlinear optical crystal which combines a number of unique features. These features include wide transparency and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity. Therefore, BBO is an excellent nonlinear crystal for frequency-doubling of Visible and Near IR laser light, OPO/OPG/OPA pumped by ultrafast pulses of wavelengths in the Near IR to UV, and sum-frequency mixing (SFM) into the Visible to the deep UV. BBO is one of the few practical crystals for use below 500 nm in SHG and SFM.
BBO crystal is also an excellent electro-optic crystal for high power applications at the wavelength range from 200nm to 2500nm. It can be used for Q-Switching in a CW diode pumped Nd:YAG laser with average power>50W.
