摘要：

The new nonlinear optical crystals BaAl2B2O7 and K2Al2B2O7 are readily grown by top-seeded flux method. BaAl2B2O7 crystallizes in the rhombohedral space group R32 (Z=3) in a cell of dimensions a=b=5.001 Angstrom, c=24.378 Angstrom and V=528.01 Angstrom(3). K2Al2B2O7 crystallizes in the trigonal space group P321 (Z=3) in a cell of dimensions a=b=8.530 Angstrom, c=8.409 Angstrom and V=529.9(2)Angstrom(3). The theoretical calculations and the measurement of nonlinear optical effect indicates that the two crystals are phase-matchable with the nonlinear optical coefficient d(11)=0.75 pm/V for BaAl2B2O7 and d(11)=0.48 pm/V for K2Al2B2O7. The birefringence of BaAl2B2O7 is Delta n=0.063 and 0.068 for K2Al2B2O7.
