FIG. 1.

The electrical circuit used for all the polarization-switching experiments, as well as for the conductivity measurements.

FIG. 2.

Conductivity map of KTP showing the ionic-current variation over the wafer.

FIG. 3.

Applied triangular electrical pulse and corresponding current flow for (a) LC-KTP and (b) HC-KTP. The dotted line in (a) is taken after the first forward poling. Since domain switching was finished at the first forward pulse, there is no switching peak in the dotted line.
