The authors have substituted aliovalent transition-metal (M = Cr, Fe, Ni, Cu, Co) and lanthanide (Ln = Er) ions that absorb visible light onto the titanium sites of the nonlinear optical materials KTiOPO{sub 4} (KTP) and RbTiOAsO{sub 4} (RTA). The substitution formally creates a charge deficiency on the Ti site. To compensate for this, the authors have substituted aliovalent counterions on the titanium (Nb), phosphorus (S, Se, Cr, Mo, W, Re) oxygen (F), or potassium (Ca, Sr, Ba, Pb) sites. The resulting new materials expand the KTiOPO{sub 4} structure field for partial replacement of one or more ions. The M and Ln ions alter the optical absorption and second harmonic properties of the materials. The ions reduce the second harmonic intensities of the isomorphs and second harmonic radiation to be phase matched at slightly shorter wavelengths than in the undoped host.
