Beta-Barium Borate (β-BaB2O4,BBO) or BBO crystal is an excellent non-linear crystal for frequency-conversion (SHG,THG, 4HG and 5HG) 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 crystals is also used in the EO Q-switches for its high electro-optical coefficients. BBO  is one of the few practical crystal for use below 500 nm in SHG and SFM.
