Available in PDF, EPUB and Kindle. Book excerpt: Optical Second Harmonic Generation (SHG) has been applied to the study of soap-like molecules adsorbed to the water-air interface. By calibrating the signal from a soluble monolayer with that of an insoluble homolog, absolute measurements of the surface density could be obtained and related to the bulk concentration and surface tension. We could then demonstrate that the soluble surfactant forms a single monolayer at the interface. Furthermore, it deviates significantly from the ideal case in that its activity coefficients are far from 1, yet those coefficients remain constant over a broad range of surface pressures. We present evidence of a first-order phase transition taking place during the adsorption of this soluble monolayer. We consider the effects of the non-ideal behavior and the phase transition on the microscopic model of adsorption, and formulate an alternative to the Langmuir picture of adsorption which is just as simple, yet it can more easily allow for non-ideal behavior. The second half of this thesis considers the problem of SHG in bulk metal vapors. The symmetry of the vapor forbids SHG, yet it has been observed. We consider several models whereby the symmetry of the vapor is broken by the presence of the laser and compare their predictions to new observations we have made using a few-picosecond laser pulse. The two-lobed output beam profile shows that it is the vapor-plus-beam combination whose symmetry is important. The dependence on vapor pressure demonstrates the coherent nature of the radiation, while the dependence on buffer gas pressure hints at a change of the symmetry in time. The time-dependence is measured directly with a preliminary pump-probe measurement. The magnitude and intensity dependence of the signal are also measured. All but one of the models are eliminated by this comparison.

This book was released on 1991 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical second harmonic generation has proven to be a powerful tool for studying interfaces. The symmetry properties of the process allow for surface sensitivity not available with other optical methods. In this thesis, we take advantage of these symmetry properties SHG to study a variety of interesting systems not previously studied with this technique. We show that optical second harmonic generation is an effective surface probe with a submonolayer sensitivity for media without inversion symmetry. We demonstrate the technique at a gallium arsenide surface, exploiting the different symmetry properties of the bulk and surface of the crystal to isolate the surface contribution. We also demonstrate that optical second harmonic generation can be used to determine the anisotropic orientational distribution of a surface monolayer of molecules. We apply the technique to study homogeneously aligned liquid crystal cells. To further explore the LC-polymer interface, we used SHG to study the surface memory effect. The surface memory effect is the rendering of an isotropic interface anisotropic by putting it in contact with an anisotropic bulk. Last, we describe some preliminary measurements of a time-resolved spectroscopic study of the phenomenon of second harmonic generation in a gas. The construction of a 500 microjoule pulsed, tunable laser source is described.
Book Synopsis Second Harmonic And Sum-frequency Spectroscopy: Basics And Applications by : Yuen Ron Shen

This book was released on 2023-02-17 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical second harmonic and sum-frequency generation has evolved into a useful spectroscopic tool for material characterization, especially as a viable and powerful technique for probing surfaces and interfaces. This book serves as an introduction on the technique. It provides a comprehensible description on the basics of the technique and gives detailed accounts with illustrating examples on the wide range of applications of the technique. It clearly points out the unique capabilities of the technique as a spectroscopic tool for studies of bulk and interface structures in different disciplines.This book is an updated version of an earlier book on the same subject, but it puts more emphasis on physical concepts and description. It underscores recent advances of sum-frequency spectroscopy at the technical front as well as over its wide range of applications, with the author's perspective in each area. Most chapters end with a section of summary and prospects that hopefully can help stimulate interest to further develop the technique and explore possibilities of applying the technique.
