Title:ExperimentalstudyonopticalparametricgenerationinsidePPLNcavity

Introduction:

Opticalparametricgenerationisanonlinearopticalprocessthatallowstheconversionofapumpwaveintotwootherwaves,calledthesignalandtheidlerwaves.Thisprocessiswidelyusedinmanyapplicationssuchasspectroscopy,telecommunications,andquantuminformationprocessing.ThePPLN(PeriodicallyPoledLithiumNiobate)isacommonlyusednonlinearcrystalfortheparametricgenerationduetoitshighnonlinearcoefficientandbroadtransparencyrange.However,theefficiencyofthisprocessislimitedbyvariousfactorssuchascrystaldefects,phasemismatch,andthermaleffects.
