Abstract

In one embodiment of the present invention, the material is a non-linear optical compound with a general chemical formula (.SIGMA..sub.i M.sub..alpha.i.sup.1)(.SIGMA..sub.j M.sub..beta.j.sup.2)(.SIGMA..sub.k M.sub..gamma.k.sup.3)Be.sub.2 O.sub.5 Formula 1 wherein M.sup.1, M.sup.2, and M.sup.3 are mono-, di-, or tri-valent metal ions respectively; wherein (.SIGMA..sub.i.beta..sub.i)=X and ranges from 0 to 6, (.SIGMA..sub.j.beta..sub.j)=Y and ranges from 0 to 3, and (.SIGMA..sub.k.gamma..sub.k)=Z and ranges from 0 to 2, (hereinafter referred to as 'MBE.sub.2 O.sub.5 ' compounds). Another embodiment of the present invention satisfies the generally formula (.SIGMA..sub.i M.sub..alpha.i.sup.1)Be.sub.2 O.sub.5 Formula 2 wherein M.sup.1 is a mono-valent metal ion; and wherein (.SIGMA..sub.i.alpha..sub.i)=X=6; and yet another embodiment of the present invention satisfies the general formula (.SIGMA..sub.j=1-3 M.sub..beta.j.sup.2)Be.sub.2 O.sub.5 Formula 3 wherein M.sup.2 is a di-valent metal ion; and wherein (.SIGMA..sub.j.beta..sub.j)=Y=3, another embodiment of the present invention satisfies the general formula (.SIGMA..sub.k M.sub..gamma.k.sup.3)Be.sub.2 O.sub.5 Formula 4 wherein M.sup.3 is a tri-valent metal ion; and wherein (.SIGMA..sub.k.gamma..sub.k)=Z=2. Mono- and di-valent metal ions, M.sup.1 and M.sup.2, 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.
