Surface 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 کاملOptical 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 from the ‘centrosymmetric’ crystals
Second harmonic generation (SHG) is a well known non-linear optical phenomena which can be observed only in non-centrosymmetric crystals due to non-zero hyperpolarizability. In the current work we observed SHG from a Zn(II) complex which was originally thought to have crystallized in the centrosymmetric space group C2/c. This has been attributed to the unequal antiparallel packing of the metal ...
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...
