研究了在Z切LiNbO/sub 3/晶体中室温下施加电压制备的铁电畴反转光栅的特性，并用于波导准相位匹配二次谐波发生（QPM SHG）器件。阐明了均匀光栅结构的可重复制造条件。制作了具有均匀光栅和扇形光栅的绿色和蓝色光器件，并对其性能进行了测试。在波长为3 mm的均匀光栅的蓝光产生装置中，获得了高达150%/W的归一化倍频效率。
The characteristics of the ferroelectric-domain-inverted gratings fabricated by applying voltage at room temperature in Z-cut LiNbO/sub 3/ crystal were examined for waveguide quasiphase-matched second-harmonic generation (QPM-SHG) devices. Conditions suitable for reproducible fabrication of uniform grating structure were clarified. Devices with uniform and fan-out grating for green and blue light generation were fabricated, and the performances were examined. A normalized SHG efficiency as high as 150%/W was obtained in blue light generation device with uniform grating of 3 mm interaction length.
