BIBO
BIBO (BiB3O6) is a newly developed Nonlinear Optical Crystal. It possesses large effective nonlinear coefficient, high damage threshold and is non-hydroscopic. Its nonlinear coefficient is 3.5 - 4 times higher than that of LBO, 1.5 -2 times higher than that of BBO. It is efficiently frequency doubling the 946nm to produce blue laser at 473nm.
