Third-harmonic generation (THGNonlinear crystalPhasematchingAn efficient optical third-harmonic generation has been observed in a single piece of nonlinear crystal. A good fit to the calculated phasematching an
One of these new frontiers opened by the laser was the field of nonlinear optics. In 1961, Franken et al. were the first to report the observation of second-harmonic generation from a quartz crystal, using ruby laser light. Third-harmonic generation (THG) was soon discovered by Terhune and...

around ten-times higher in the forward direction than sideways. The third-harmonic ellipticity was as high as 3° and we attribute this effect to the interference of chiral and achiral effective nonlinear susceptibility tensor components. Third-harmonic Mie scattering on semiconductor helices opens a ...
The optical properties of conjugated π-electron system materials are often much more nonlinear than inorganic solids because of their electronic structure; they also show many NLO properties and faster/higher NLO responses [15]. Besides, the molecules with a non-centrosymmetric crystal structure are ...
Graphene with massless Dirac fermions can have exceptionally strong third-order optical nonlinearities. Yet reported values of nonlinear optical susceptibilities for third-harmonic generation (THG), four-wave mixing (FWM) and self-phase modulation vary o
We then show that these resonances lead to a large enhancement of third-harmonic generation by a factor of nearly 104 times compared to silicon films of the same thickness. The introduced flat-band design unlocks new potential for a broad range of applications, including nonlinear imaging, ...
