Beta Barium Borate (BBO)
BBO (Beta Barium Borate, β-BaB2O4) is a nonlinear optical crystal with a combination of unique features, making it an ideal choice for frequency mixing and other nonlinear optical applications. It combines wide transparency and phase matching ranges, a large nonlinear coefficient, high damage threshold and excellent optical homogeneity.
BBO is particularly well suited to frequency conversion of high peak or high average power laser radiation and is a popular choice for use with Nd:YAG lasers along with Ti:Sapphire, copper vapour, argon ion, Ti:Sapphire and dye lasers.
Roditi supplies BBO crystals in a variety of sizes, in both phase matching types. In addition, a range of mounts is available to hold the crystals, helping to prevent damage and ensure easy handling.
