摘要： Nonlinear optical materials having the general formula Ca.sub.1.40-X M.sub.X V.sub.0.98.+-.0.05 O.sub.4.00.+-.0.08 wherein X is 0.07 to 0.43 and M is selected from the group consisting of Bi, La, Ce, Y, Pm, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, and mixtures thereof are described. Compositions satisfying this formula belong to the space group R3c wherein a=b=10.8.+-.0.1 .ANG., and c=38.0.+-.0.3 .ANG.. These NLO compositions are capable of doubling the frequency of light at about 0.1 to about 3.3 times the efficiency of KH.sub.2 PO.sub.4 (KDP). No damage to the NLO material is observed when they are exposed to high-power lasers.
