        BiB3O6 (BIBO) Crystal

        BIBO( BiB3O6) is a newly developed nonlinear Optical Crystal. It possesses large effective nonlinear coeffcient,high damage threshold and inertness with respect to moisture.Its nonlinear coefficient is 3.5-4 times higher than that of LBO,1.5-2 times higher than that of BBO. It is a promising doubling crystal to produce blue laser.The top-seeded solution growth (TSSG) technique is used at CASTECH for the growth of BIBO single crystals.
