Parity-forbidden excitations of Sr(2)CuO(2)Cl(2) revealed by optical third-harmonic spectroscopy.
We present the first study of nonlinear optical third-harmonic generation (THG) in the strongly correlated charge-transfer insulator Sr(2)CuO(2)Cl(2). For fundamental excitation in the near infrared, the THG spectrum reveals a strongly resonant response for photon energies near 0.7 eV. Polarization analysis reveals this novel resonance to be only partially accounted for by three-photon excitati...
متن کاملOptical-parametric-oscillator solitons driven by the third harmonic.
We introduce a model of a lossy second-harmonic-generating (chi(2)) cavity externally pumped at the third harmonic, which gives rise to driving terms of a new type, corresponding to a cross-parametric gain. The equation for the fundamental-frequency (FF) wave may also contain a quadratic self-driving term, which is generated by the cubic nonlinearity of the medium. Unlike previously studied pha...
متن کاملOptical 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 کاملVisualize susceptibility information with third harmonic generation microscopy and spectroscopy
Third harmonic generation (THG) microscopy and spectroscopy was a modality suitable for in vivo clinical imaging and molecular analysis, due to their characteristics of high penetration depth, high resolution, and no energy deposition [1]. Our previous study indicated that THG spectra depend on nonlinear susceptibility (χ3), which is related to the absorption characteristics of a molecule, due ...
متن کاملEffect of Kondo resonance on optical third harmonic generation
We use the method of dynamical mean field thoery, to study the effect of Kondo resonance on optical third harmonic generation (THG) spectra of strongly correlated systems across the metal-insulator transition. We find that THG signals are proportional to the quasiparticle weight z of the Kondo peak, and are precursors of Mott-Hubbard gap formation. PACS 42.65.-k; 71.27.+a; 71.30.+h
