Surface-wave harmonic generation on <i>y</i>-<i>z</i>, <i>x</i>-<i>z</i>, and 41 1/2-<i>x</i> lithium niobate

Abstract

Optical probing was used to evaluate the coefficient for surface-wave harmonic generation on three high-coupling cuts of lithium niobate, namely, y-z, x-z, and 41 1/2-x. Surface-wave attenuation and acoustic beam diffraction profiles of the fundamental and second harmonic were also measured.
