Optical second harmonic generation study of vicinal Si(111) surfaces

Vicinal Si(111) surfaces studied by optical second-harmonic generation: Step-induced anisotropy and surface-bulk discrimination.

Optical second harmonic generation properties of BiB3O6.

We present studies of the optical properties of the new nonlinear material BiB3O6 for second harmonic generation from the visible to infrared. We have determined the phase-matching conditions and effective nonlinear coefficients in the three principal optical planes, acceptance bandwidths, spatial and temporal walkoff, group velocity dispersion and double phase-matching behaviour. We also repor...

Optical second harmonic generation chiral spectroscopy.

Chiral spectroscopic study: The intensities of second harmonic generation chiral spectroscopy are obtained from the dispersion of the nonlinear optical susceptibility components, as a function of wavelength for helicenbisquinone thin films (see figure). A single formalism fits all the data simultaneously, and the findings constitute an important milestone towards the development of a new experi...

Microscopic measurement of second harmonic generation from chiral surfaces.

A microscopic measurement system of circular dichroic spectra of second harmonic generation, which is applicable to detect the chirality of micro-region of molecular aggregates, has been investigated. The performance of the system was demonstrated by the discrimination of chirality of molecular aggregates of porphyrin on a glass plate.
