Third Harmonic Generation in Cuprous Oxide: Efficiency Determination
Abstract
The efficiency of third harmonic generation in cuprous oxide was measured. Intensities followed a non-cubic power law which indicates nonperturbative behavior. Polarization anisotropy of the harmonic generation was demonstrated and related to the third order susceptibility. The results will influence the understanding of harmonic generation in centrosymmetric materials and are potentially relevant to device design and the interpretation of exciton behavior.
