Available in PDF, EPUB and Kindle. Book excerpt: Laser-induced surface excitations on a grating are studied in terms of the solution to Maxwell's equations. A rigorous theory, derived originally for a lamellar grating, is used to study the resonance phenomenon for deep gratings. The generalization of the square-well grating to gratings of arbitrary shapes is examined numerically. A new diffraction anomaly is seen to occur when the grating depth is approximately equal to half of the wavelength of the incident laser radiation.

Book Synopsis Theoretical Aspects of Laser-Induced Periodic Surface Structure Formation by : M. Hutchinson
Download or read book Theoretical Aspects of Laser-Induced Periodic Surface Structure Formation written by M. Hutchinson and published by . This book was released on 1983 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser-induced periodic pattern formation has been observed on a variety of substances. In particular, low-power laser have been used to deposit a pattern on a metal surface. For a relatively smooth surface grating, this pattern can be explained in terms of a perturbative solution of Maxwell's equations. However, as the surface grating is enhanced by this initial deposition, the perturbation solution breaks down. An alternate non-perturbative solution of Maxwell's equations for such rough surfaces is considered here. Moreover, other possible mechanisms that may assist pattern formation are discussed, such as field-enhanced evaporation and surface migration. (Author).
Book Synopsis Laser-Induced Dynamic Gratings by : Hans Joachim Eichler
Download or read book Laser-Induced Dynamic Gratings written by Hans Joachim Eichler and published by Springer. This book was released on 2013-06-29 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invention ofthe laser 25years ago resulted in powerfullight sources which led to the observation of unexpected and striking phenomena. New fields of science such as holography and nonlinear optics developed constituting the basis of this volume. The classical principle of linear superposition of light wavesdoes not hold anymore. Two laser beams crossing in a suitable material may produce a set of new beams with different directions and frequencies. The interaction of light waves can be understood by considering the optical grating structures which develop in the overlap region. The optical properties of matter become spatially modulated in the interference region of two light waves. Permanent holographic gratings have been produced in this way by photographic processes for many years. In contrast, dynamic or transient gratings disappear after the inducing light source, usually a laser, has been switched off. The grating amplitude is controlled by the light intensity. Dynamic gratings have been induced in a large number ofsolids, liquids, and gases, and are detected by diffraction, 'forced light scattering' of a third probing beam, or by self-diffraction of the light waves inducing the grating. The combined interference and diffraction effect corresponds to four-wave mixing (FWM) in the language of nonlinear optics. The process is called degenerate ifthe frequenciesofthe three incident wavesand the scattered wave are equal. Degenerate four-wave mixing (DFWM) is a simple method to achieve phase conjugation, i.e. to generate a wave which propagates time reversed with respect to an incident wave.

Book Synopsis Laser-Induced Reflectance Transient Gratings Method by : Mansoureh Ganjali
Download or read book Laser-Induced Reflectance Transient Gratings Method written by Mansoureh Ganjali and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of theoretical and experimental studies of thermal and acoustic gratings excited at two media interface have been presented in the work. One medium is highly absorbing substance whereas another is transparent one at the spectral range of excitation and probing beams used. All the investigations have been conducted under reflecting configuration of probe beam. Aim of the work is to elaborate and experimentally implement the methods for thermal characterization and temperature remote sensing of metal and narrow band gap semiconductor surfaces, thin films as well as adjacent transparent gases and liquids. In-plane thermal diffusivity of nanocrystalline diamond film on substrate has been measured for the first time. It has been shown that in order to minimize the substrate influence on the results of measurements the grating spacing should be as small as comparable to film thickness. The sensivity of diffracted beam detection have to be increased at the same time. Method of out-of-plane thermal diffusivity of thin dielectric films that are transparent in spectral range used has been proposed and tested under modeling condition. It has been experimentally...

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors Probed by Ultrafast Laser Spectroscopy, Volume 1 discusses the use of ultrafast laser spectroscopy in studying fast physics in semiconductors. It reviews progress on the experimental and theoretical understanding of ultrafast events that occur on a picosecond and nanosecond time scale. This volume first explores the relaxation of energy and the momentum of hot carriers and then turns to relaxation of plasmas and phonons. It also discusses the dynamics of excitons, polaritons, and excitonic molecules and reviews transient transport and diffusion of carriers. Scientists, engineers, and graduate students will find this book invaluable.
