One crystal has principle crystal axes that are oriented for type-I second-harmonic generation. The ultraviolet laser beam exits the optic through an uncoated surface of the other crystal. The principle crystal axes of the two crystals have different orientations and have reflection symmetry about ...

Resonant enhancements of second‐harmonic generation under normal incidence of light of up to two orders of magnitude with respect to the same laminate metamaterial on a glass substrate under oblique incidence of light are found experimentally. The nonlinear optical resonances in the range of 800–...

The second harmonic generation (SHG) in the ferroelectric liquid crystal (FLC) state has been studied as functions of electric field strength, rotating angle, temperature and molecular structure. It has been confirmed that a sharp angularly phase-matching curve of the SHG controlled by an electric...
We present phase-matched, second-harmonic generation in the ferroelectric liquid-crystal material SCE9 (manufactured by BDH Ltd.). From the analysis of these results, the absolute values of all nonzero components of the d tensor have been obtained. A direct comparison between this material and ...

Second-harmonic generation in the layered semiconductor GaS excited with the wavelength λ = 1579 nm is investigated with the Maker fringe technique. It is shown that the second-harmonic signal originates from domains in the crystal, which consist of the noncentrosymmetric C 5 3 v polytype. The...
