BIBO

BIBO (Bismuth Borate or BiB3O6) does great performances in possessing large effective nonlinear coefficient, high damage threshold and it 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. Uniquely, when BIBO is frequency-doubling the 946nm to produce blue laser at 473 nm, it represents great efficiency.

Advantages

● Broad transparency range from 286nm to 2500nm

● High optical homogeneity and being free of inclusion

●Large effective SHG coefficient (about 9 times that of KDP)

● High damage threshold

● Wide temperature-bandwidth

● Non hygroscopic
