In one embodiment of the present invention, the material is a non-linear optical compound with a general chemical formula (ΣiMαi1)(ΣjMβj2)(ΣkMγk3)Be2O5 Formula 1 wherein M1, M2, and M3 are mono-, di-, or tri-valent metal ions respectively; wherein (Σiβi)=X and ranges from 0 to 6, (Σjβj)=Y and ranges from 0 to 3, and (Σkγk)=Z and ranges from 0 to 2, (hereinafter referred to as “MBE2O5” compounds). Another embodiment of the present invention satisfies the generally formula (ΣiMαi1)Be2O5 Formula 2 wherein M1 is a mono-valent metal ion; and wherein (Σiαi)=X=6; and yet another embodiment of the present invention satisfies the general formula (Σj=1-3Mβj2)Be2O5 Formula 3 wherein M2 is a di-valent metal ion; and wherein (Σjβj)=Y=3, another embodiment of the present invention satisfies the general formula (ΣkMγk3)Be2O5 Formula 4 wherein M3 is a tri-valent metal ion; and wherein (Σkγk)=Z=2. Mono- and di-valent metal ions, M1 and M2, that are suitable for forming compounds satisfying the general formula are preferably independently selected from the group consisting of Groups IA and IIA, however other mono- and di-valent cations may be used so long as the material has a non-centrosymmetric arrangement.
A non-centrosymmetric composition comprising the general formula (ΣiMαi1)(ΣjMβj2)(ΣkMγk3)Be2O5 for use in a non-linear optics application, wherein M1, M2, and M3 are mono-. di- and tri-valent metal ions respectively;
A method for making a non-centrosymmetric compound with the general formula (ΣiMαi1)(ΣjMβj2)(ΣkMγk3)Be2O5 for use in a non-linear optics application, wherein M1, M2 and M3 are mono-, di- and tri-valent metal ions respectively;
A method for making a non-centrosymmetric compound with the general formula (ΣiMαi1)(ΣjMβj2)(ΣkMγk3)Be2O5 for use in a non-linear optics application, wherein M1, M2, and M3 are mono-, di- and tri-valent metal ions respectively;
A non-centrosymmetric compound of formula selected from the group consisting of Li6Be2O5, Na3Li3Be2O5, Na6Be2O5, K3Na3Be2O5, K6Be2O5, and Cs6Be2O5.
A non-centrosymmetric composition comprising the general formula (ΣiMαi1)(Σj Mβj2)(ΣkMγk3)Be2O5 for use in a non-linear optics application, wherein M1, M2 and M3 are mono-, di- and tri-valent metal ions respectively;
