08 Nov 2012 BBO (Beta Barium Borate, β-barium borate or β-BaB2O4) is a nonlinear crystal that offers very wide transparency, moderately high nonlinear coupling, high damage threshold and good chemical and mechanical properties. BBO phase matches over a wide spectral range, yielding SHG, 3rd, 4th and 5th generation from 190 up to 1780 nm.
OPOs and OPAs based on BBO crystals are powerful tools for generating a widely tunable coherent radiation from the UV to IR.
