Beta Barium Borate, often abbreviated as BBO, is a nonlinear optical crystal with the chemical formula BaB2O4. It belongs to the trigonal crystal system and exhibits excellent transmission across a broad range of wavelengths, making it particularly well-suited for various optical applications. Its unique nonlinear optical properties have positioned BBO as a promising component in the development of cutting-edge technologies.
Hangzhou Shalom EO offers the stocked and customized BBO (Beta Barium Borate) crystals 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. Hangzhou Shalom EO also provides BBO crystals used in the EO Q-switches with high-precision polishing and Cr-Au electrodes furnished and spontaneous down conversions (SPDC) applications. BBO is one of the few crystals for use below 500nm in SHG and SFM.
