Optical Second Harmonic Generation as a Probe of Surface Chemistry
Optical second harmonic generation (SHG) is the nonlinear conversion of two photons of frequency w to a single photon of frequency 2w which, in the electric dipole approximation, requires a noncentrosymmetric medium. The ability of noncentrosymmetric crystals to produce SHG has led to their implementation as frequency doublers in a wide variety of laser systems. SHG can also be obtained from th...
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 کاملSymmetry superposition studied by surface second-harmonic generation.
The components of a third-rank g' ' tensor have been split into contributions due to 1-fold, 2fold, 3-fold, and (x}-fold or isotropic rotation axes for a surface of C, symmetry. Theoretical analysis of the rotation patterns obtained by the surface second-harmonic (SH) generation indicates that a complete symmetry analysis cannot be performed without knowledge of the relevant distribution functi...
متن کاملSurface area-dependent second harmonic generation from silver nanorods.
The nonlinear optical (NLO) properties of metallic nanoparticles strongly depend on their size and shape. Metallic gold nanorods have already been widely investigated, but other noble metals could also be used for nanorod fabrication towards applications in photonics. Here we report on the synthesis and NLO characterization of silver nanorods (AgNRs) with controllable localized surface plasmon ...
متن کاملInterferometric second harmonic generation microscopy.
We describe a novel second harmonic generation (SHG) microscope that employs heterodyne detection by interfering the epi directed SHG from a sample with SHG from a reference crystal. In addition, the microscope provides complementary reflectance information based on optical coherence microscopy (OCM). The instrument features dual balanced detection to minimize the effect of source fluctuations,...
