BIBO Crystal

BIBO has a large effective nonlinear coefficient which is 3.5 - 4 times higher than that of LBO, 1.5 - 2 times higher than that of BBO. 

Product Details:

Bismuth Triborate (BiB3O6 or BIBO) is a newly developed nonlinear optical crystal. It possesses large effective nonlinear coefficient, 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.
