I-waveplate ye-wavelength ephindwe kabini isetyenziswa ngokubanzi kwinkqubo yesiThathu yeHarmonic Generation (THG).Xa ufuna ikristale ye-NLO yohlobo lwe-II SHG (o+e→e), kunye nekristale ye-NLO yohlobo lwe-II THG (o+e→e), i-polarization ephumayo esuka kwi-SHG ayinakusetyenziselwa i-THG.Ke kuya kufuneka ujike i-polarization ukuze ufumane i-polarization emibini ye-perpendicular yohlobo lwe-II THG.I-waveplate yobude obubini busebenza njenge-polarizing rotator, inokujikelezisa i-polarization yomnye umqadi kwaye ihlale iyenye i-polarization yomqadi.
