Beta-Barium Borate (β-BaB2O4) or BBO crystal has excellent combination of optical properties: high damage threshold, large nonlinear coefficients, broad transmission range, wide phase matching, low thermal-optical coefficients and availability of large size high quality single crystals. BBO crystals is a versatile nonlinear crystals, suitable for harmonic generation operations, optical parametric oscillators (OPO) and optical parametric amplifiers (OPA), and electric optical applications. BBO is one of the few practical crystal for use below 500nm in SHG and SFM. 

Hangzhou Shalom EO offers off-the-shelf and customized BBO crystals for frequency-conversion (SHG,THG, 4HG and 5HG) of Visible and Near IR laser light (such a as Na:YAG lasers, Ti:Sapphire lasers), 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 (dye lasers). Hangzhou Shalom EO also provides BBO crystals used in the electric optical pockels cells and spontaneous down conversions (SPDC) applications.
