Abstract

We show that when a laser beam is tightly focused on a single boundary between two 180° anti-parallel ferroelectric domains, a strong enhancement of the Čerenkov second-harmonic generation in the direction perpendicular to the boundary occurs. Using this effect we develop a scanning Čerenkov second-harmonic microscopy which allows direct, three-dimensional and nondestructive imaging of the inverted domain pattern with sub-micrometer resolution.
