چکیده انگلیسی
In this study, the amount of decrease in coercive field of congruent lithium niobate during repeated poling and back-poling was measured. The polarization is reversed in 300Â ms and then back-poled during the rest period. The coercive field can be decreased around 1Â kV/mm with a repeated poling interval of 5Â s. As the interval prolonged, the poling field decrease became smaller, and a stretched exponential function is suggested for the experimental fitting resulting in a set of meaningful parameters. These values are essential for the design of high quality domain engineering.
