BIBO( BiB3O6) Crystal is a newly developed Nonlinear Optical Crystal. It features a large effective nonlinear coefficient, a high damage threshold, and inertness to moisture. Its nonlinear coefficient is 3.5-4 times higher than that of LBO, and 1.5-2 times higher than that of BBO. It is a promising SHG crystal to generate blue laser output.
