NGAB crystal index n o, n e at some specifical wavelengths and its temperature coefficient, which are measured with the combination of minimum deviation and fixed incident angle, are reported. The crystal dispersion equation is given, and its phase-matching angle at the wavelength 1.064～μm is calculated. More than 5～mW of the output power at 0.53～μm is obtained from a NGAB crystal with volume 3～mm×3～mm×5～mm, pumped by LD; its light-light conversion efficiency is 0.5%, and the output at 1.064～μm is 214～mW, the conversion efficiency is 26%.
