Third Harmonic Generation in Cuprous Oxide: Efficiency Determination

Laszlo Frazer, Richard D. Schaller, Kelvin Chang +2

The efficiency of third harmonic generation in cuprous oxide was measured. Intensities followed a non-cubic power law which indicates nonperturbative behavior. Polarization anisotr…
