electric-field-induced second harmonic generation ~ESHG! vibrational second hyperpolarizability of CF4. With the exception of the small ESHG vibrational second hyperpolarizability the infinite optical frequency method
The frequency-dependent vibrational second hyperpolarizability of CH42nFn molecules with n 50 – 4 has been computed for the most common nonlinear optical ~NLO! processes by adopting the perturbation approach due to Bishop and Kirtman @J. Chem. Phys. 95, 2646 ~1991!#. These calculations have been performed by using the Sadlej atomic basis set with the Hartree-Fock technique as well as with the M...
متن کاملOptimization of the molecular hyperpolarizability for second harmonic generation in chiral media
Molecular properties leading to second harmonic generation in chiral media in the electric dipole approximation for the cases of axial and biaxial symmetry are described. The components of the hyperpolarizability tensor that transform like a second-rank pseudotensor (L 2) and a third-rank tensor (L 3) contribute. The sum-over-states quantum formula for the hyperpolarizability is used to ill...
متن کاملSecond-harmonic generation
The goal of this experiment in nonlinear optics is to study the conversion of a (very small) fraction of laser light from its original wavelength of 980 nm (i.e. invisible to the naked eye) to its second-harmonic at a wavelength of 490 nm. This conversion takes place by mild focussing of an intense laser beam in a nonlinear birefringent crystal of BBO (= β BaBO4). You will study the physical pr...
متن کاملTheory of Second-Harmonic Generation in Colloidal Crystals
On the basis of the Ewald-Kornfeld formulation, we study the effective susceptibility of second-harmonic generation (SHG) in colloidal crystals, which are made of graded metallodielectric nanoparticles with an intrinsic SHG susceptibility suspended in a host liquid. We find a large enhancement and redshift of SHG responses, which arises from the periodic structure, local field effects, and grad...
متن کاملSqueezed light from second-harmonic generation: experiment versus theory.
We report excellent quantitative agreement between theoretical predictions and experimental observation of squeezing from a singly resonant second-harmonic-generating crystal. Limitations in the noise suppression imposed by the pump laser are explicitly modeled and confirmed by our measurements.
