BBO Crystals Custom and Stock

Hangzhou Shalom EO offers the stocked and customized BBO 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 and spontaneous down conversions (SPDC) applications. BBO is one of the few practical crystal for use below 500nm in SHG and SFM.
