Product Features
01
BIBO (BiB3O6) is a newly developed Nonlinear Optical Crystal. It possesses large effective nonlinear coefficient, high damage threshold and is non-hydroscopic.
02
It's nonlinear coefficient is 3.5 - 4 times higher than that of LBO, 1.5 -2 times higher than that of BBO. It can efficiently frequency doubling the 946nm to produce blue laser at 473nm.
