ABSTRACT:
A material for harmonic generation has been made by substitutional changes to the crystal LaCa4(BO3)3also known as LaCOB in the form Re1xRe2yRe3zCa4(B03)3O where Re1 and Re2, (rare earth ion 1 and rare earth ion 2) are selected from the group consisting of Sc, Yttrium, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; Re3 is Lanthanum; and x+y+z=1.
