Beta-barium borate (BBO) is a versatile nonlinear crystal ideally suited for nonlinear laser interactions. BBO crystals combine very wide transparency, moderately high nonlinear coupling, high damage threshold and good chemical and mechanical properties. BBO phase matches over a wide range, yielding SHG, SFD and OPO from 190 to 1780 nm.
