Nonlinear optical crystal BiAlGa2(BO3)4

The new nonlinear optical crystals BiAlGa2(BO3)4 have been grown by spontaneous crystallization with molten flux based on a Bi2O3–B2O3 solvent. From single crystal X-ray diffraction measurement, BiAlGa2(BO3)4 has been found to crystallize in the trigonal huntite structure type, space group R32, with cell dimensions a = 9.4433(9) and c = 7.4130(10) Å. The diffuse reflectance spectrum on a powder sample indicated that the short-wavelength absorption edge of BiAlGa2(BO3)4 extends to approximately 271 nm. Second-harmonic generation (SHG) on powder samples has been measured using Kurtz and Perry technique, which indicated that BiAlGa2(BO3)4 is a phase-matchable material, and its SHG coefficient is measured to be four times as large as that of KDP.
