ABSTRACT

When external field was applied to congruent LiNbO3, it was investgated for domain formation and expansion of LiNbO3. The domain wall velocities of 0.5 mm thickness LiNbO3 were 28.70, 16.02 and 5.75 μm/sec under poling field of 23.5, 22.0 and 21.0 kV/mm, respectively. As 1 MΩ resistor was used in domain inversion system, harmonic domain inversion was not achieved by rapid domain expansion. And 50 % duty cycle periodically poled LiNbO3 have been fabricated by charge control using 10 MΩ resistor.@
