Nonlinear single crystal ß-Barium Borate (beta-BaB2O4 or BBO) is an excellent optical nonlinear crystal developed recently. It exhibits broad phase matching range, high non-linearity (about 6 times more than that of KDP), high optical damage threshold, good mechanical and temperature stability. This nonlinear trigonal uniaxial crystal possesses wide transparency range from 190 nm up to 2500 nm.

APPLICATIONS of nonlinear single crystal ß-Barium Borate (beta-BaB2O4 or BBO):

- For harmonic generation (SHG, THG, 4HG, 5HG) of Nd:YAG laser, SHG, THG of Ti: Sapphire, Alexandrite lasers
- For tunable solid state lasers using OPO (pumped by 355, 532 or 1064 nm)
- For UV sources from SHG, SFG of dye lasers
- For autocorrelation (in thin plates) in shortpulse (ps and fs) lasers
