Extended phase matching of second-harmonic generation in periodically-poled KTiOPO4 with zero group-velocity mismatch
Under extended phase-matching conditions, the first frequency-derivative of the phase-matching function is zero and the phase-matching bandwidth is greatly increased. We made extensive three-wave mixing measurements to identify the operating point for extended phase matching, thus permitting us to observe a type-II phase-matching bandwidth of 100 nm centered at the fundamental wavelength of 158...
متن کاملGeneration of second-harmonic conical waves via nonlinear bragg diffraction.
We report on the observation of second-harmonic conical waves generated in a novel geometry of the transverse excitation of an annular periodically poled nonlinear photonic structure by a fundamental Gaussian beam. We show that the conical beams are formed as a result of the higher-order nonlinear Bragg diffraction involving two parametric processes in which an ordinary fundamental wave is conv...
متن کاملSpatiotemporal toroidal waves from the transverse second-harmonic generation.
We study the second-harmonic generation via transversely matched interaction of two counterpropagating ultrashort pulses in chi(2) photonic structures. We show that the emitted second-harmonic wave attains the form of spatially expanding toroid with the initial thickness given by the cross correlation of the pulses. We demonstrate the formation of such toroidal waves in crystals with random fer...
متن کاملSecond-harmonic generation
The goal of this experiment in nonlinear optics is to study the conversion of a (very small) fraction of laser light from its original wavelength of 980 nm (i.e. invisible to the naked eye) to its second-harmonic at a wavelength of 490 nm. This conversion takes place by mild focussing of an intense laser beam in a nonlinear birefringent crystal of BBO (= β BaBO4). You will study the physical pr...
متن کاملVoltage-controlled phase matching in quadrupole second-harmonic generation.
We have observed strong phase-matched (PM) quadrupole optical second-harmonic generation (SHG) from nematic liquid crystals that possess inversion symmetry. PM conditions were achieved for two configurations by voltage control of the molecular orientation and thus of the refractive indices. Quadrupole SHG was separated from electric-field-induced dipole-type SHG with the help of time-gated meas...
