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...
متن کاملOptical 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...
متن کاملSecond Harmonic Generation Diagnostic of Layer by Layer Deposition from Disperse Red 1–Functionalized Maleic Anhydride Copolymer
Layer-by-layer (LBL) electrostatic assembly of poly-electrolytes is proving to be an increasingly rich and versatile technique for the formation of multilayered thin films with a wide range of electrical, magnetic, and optical properties. In the present work we synthesized a new nonlinear optical (NLO) maleic acid copolymer containing Disperse Red 1 moieties, built-up multilayer assemblies by a...
متن کاملProbing symmetry properties of few-layer MoS2 and h-BN by optical second-harmonic generation.
We have measured optical second-harmonic generation (SHG) from atomically thin samples of MoS2 and h-BN with one to five layers. We observe strong SHG from materials with odd layer thickness, for which a noncentrosymmetric structure is expected, while the centrosymmetric materials with even layer thickness do not yield appreciable SHG. SHG for materials with odd layer thickness was measured as ...
متن کاملOptical Second Harmonic Generation in a Whispering Gallery Mode Resonator
We are developing high quality factor whispering gallery mode resonator (WGMR) disks for use in quantum information experiments. Our polished lithium niobate disks achieved a quality factor on the order of 10. We report the use of Type-I noncritical phase matching in a lithium niobate whispering gallery mode resonator disk to produce optical second harmonic generation at λ = 532nm. This process...
