BBO nonlinear optical crystals – LASER CRYLINK
Description
BBO Crystal is a
one of the most important nonlinear optical crystals, beta-barium borate
(β-BaB2O4，β-BBO) combines many outstanding features
such as its high nonlinear optical coefficients, low group-velocity dispersion,
broad transparency range (189–3500 nm) and high damage threshold. This unique
combination ensures β-BBO crystal a promising candidate for a wide range of
nonlinear optical applications such as frequency converters and optical
parametric oscillators. In the realm of quantum optics, β-BBO crystal can be
used to generate entangled photon pairs and ten-photon entanglement. click here
BBO nonlinear
crystal is a negative uniaxial crystal, which provides phase matching for
various second-order interactions almost over its entire transparency range
(from 185 nm to 3.3 µm, as deduced from the transmittance measurements using
crystal samples of several mm thickness), making it a widely used crystal for
nonlinear frequency conversion in the ultraviolet, visible and near-infrared.
In that regard, BBO crystal is the most important nonlinear crystal for near
infrared optical parametric chirped pulse amplifiers, which currently deliver
few optical cycle pulses with high average and ultrahigh peak powers.
