Inclusion Tuning of Nonlinear Optical Materials: KTP (Potassium Titanyl Phosphate) Isomorphs

KTiOPO4 or KTP has shown itself to be a premier material for optical second harmonic generation, or SHG. Cations ranging in size from Ag+ to Cs+ can be partially or completely exchanged for Kt, altering the structure and changing the reactivity and SHG coefficient of the material. In particular, par...

Description
Summary:KTiOPO4 or KTP has shown itself to be a premier material for optical second harmonic generation, or SHG. Cations ranging in size from Ag+ to Cs+ can be partially or completely exchanged for Kt, altering the structure and changing the reactivity and SHG coefficient of the material. In particular, partial deammoniation of NH4TiOPO4 results in changes in the Ti-O bond lengths and a dramatic reduction in SHG. Many isomorphic derivatives of KTP have been made in which 3- and 4- valent transition and main group metals are substituted for Ti, balancing charge by substituting Fu or OH for oxide in the Ti-O chain. Guest and host modification can be used to define nonlinear optic properties over a wide range.
