Second-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 کاملSpatial mode discrimination using second harmonic generation.
Second harmonic generation (SHG) can be used as a technique for controlling the spatial mode structure of optical beams. We demonstrate experimentally the generation of higher-order spatial modes, and the possibility to use nonlinear phase matching as a predictable and robust technique for the conversion of transverse electric modes of the second harmonic output. The details of this effect are ...

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 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,...
