Abstract
We study experimentally the erenkov second-harmonic generation in an optical superlattice formed in periodically poled lithium niobate crystal. We demonstrate strong sensitivity of the erenkov signal to the wavelength, diameter, and position of the incident fundamental beam. We model the observed behavior by using simple approach based on multiple interference of second harmonic signals emitted from the vicinity of the domain walls.
