BBO is an excellent non-linear crystal for frequency-doubling (SHG) 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. BBO is also one of the few practical crystal for use below 500 nm in SHG and SFM, it can be widely used in medical, military and meteorology fields.
