β-BBO Crystal—a widely used nonlinear crystal for frequency conversion in the ultraviolet, visible and near-infrared

BBO Crystal is one of the essential nonlinear optical crystals. Beta-barium borate (β-BaB2O4, β-BBO) combines many outstanding features such as its high nonlinear optical coefficients and low group-velocity dispersion, broad transparency range (189–3500 nm) high damage threshold. This unique combination ensures that β-BBO crystal is a promising candidate for nonlinear optical applications such as frequency converters and optical parametric oscillators. In quantum optics, β-BBO crystal can generate entangled photon pairs and ten-photon entanglement.

BBO nonlinear crystal is a negative uniaxial crystal. It provides phase matching for various second-order interactions almost over its entire transparency range. This transparency ranges from 185 nm to 3.3 µm, as inferred from transmittance measurements using crystal samples of a few mm thicknesses. It is widely used for nonlinear frequency conversion in the ultraviolet, visible, and near-infrared. The BBO crystal is the most critical nonlinear crystal for near-infrared optical parametric chirped-pulse amplifiers, which currently deliver few optical cycle pulses with high average and ultrahigh peak powers.
