BIBO
BIBO (BiB3O6) is a newly developed nonlinear optical (NLO) crystal, which has excellent characteristics for nonlinear optical applications. BIBO has a broad transparency range, from 286nm to 2500nm, a high optical homogeneity (n10-6cm) and is free of inclusions. BIBO's effective SHG coefficient is about 9 times that of KTP. In addition, BIBO has a high damage threshold, wide temperature bandwidth and inertness with respect to moisture.
