Laser technology and holography Books

Book SynopsisThere is evidence to suggest that our world and everything in it from snowflakes to maple trees to falling stars and spinning electrons are only ghostly images, projections from a level of reality literally beyond both space and time.'This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protégé of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing.In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe and in other universes beyond our own.Trade Review‘One of the cleverest writers around today…his eclectic mind ranges far into the deepest and often most controversial mysteries of modern science.’ Fred Alan Wolf PhD, author of ‘Taking the Quantum Leap’Table of ContentsPart 1 A remarkable new view of reality: the brain as hologram; the cosmos. Part 2 Mind and body: the holographic model and psychology; I sing the body holographic; a pocketful of miracles; seeing holographically. Part 3 Space and time: time out of mind; travelling in the superhologram; return to the dreamtime.

Book SynopsisFuture microwave, wireless communication systems, computer chip designs, and sensor systems will require miniature fabrication processes in the order of nanometers or less as well as the fusion of various material technologies to produce composites consisting of many different materials. This requires distinctly multidisciplinary collaborations, implying that specialized approaches will not be able to address future world markets in communication, computer, and electronic miniaturized products.Anticipating that many students lack specialized simultaneous training in magnetism and magnetics, as well as in other material technologies, Magnetics, Dielectrics, and Wave Propagation with MATLABR Codes avoids application-specific descriptions, opting for a general point of view of materials per se. Specifically, this book develops a general theory to show how a magnetic system of spins is coupled to acoustic motions, magnetoelectric systems, and superconductors.Table of Contents1.

Book SynopsisThis research monograph is a companion edition and update to the book: L. C. Andrews and R. L. Phillips, Laser Beam Propagation through Random Media, 2nd edition (SPIE Press, 2005). We present several new and advanced topics that have emerged during the years since the 2005 title was published. Much of the new material is compared throughout the text with experimental and computer simulation data. This comparison includes beam wander and its effect on a propagating laser beam, including beam-wander-induced scintillation. Other additions include an assessment of conventional probability density function (PDF) models for the irradiance after passing through a finite receiver aperture. New mathematical models for enhanced backscatter are introduced here, including extension to strong fluctuation regimes and semi-rough targets. In recent years, scientists have found experimental evidence that non-Kolmogorov and anisotropic conditions may occur even along horizontal propagation paths near the ground. We include a chapter on these important topics that presents a detailed treatment involving both non-Kolmogorov and anisotropic models. The book ends with a chapter devoted to the discussion of commonly used instruments for measuring atmospheric parameters like the refractive-index structure parameter, inner scale, temperature, wind speed, heat flux, and so forth.

Book SynopsisDue to their unique flexibility and high reproducibility, lasers have been traditionally used in processes such as cutting, drilling, machining, welding or cladding. In recent years, with the development of ultrafast laser sources, (ie: laser sources emitting pulses with durations ranging from picoseconds to femtoseconds), lasers also emerged as a new and promising tool for the texturing of virtually all kinds of surfaces. In Chapter One, a brief overview of the lasers and techniques utilised in micro- and nano-surface modifications is presented, followed by a detailed discussion of the surface chemistry and topography effect on bacteria aggregation and adhesion. Also, the role of the laser-induced superficial patterns on the response and sensitivity of bio-implants will be explored in depth. Chapter Two reports on cardiovascular laser application by using the open-irrigated ELMA catheter RytmoLas as an intriguing alternative for catheter ablation of arrhythmias. Chapter Three describes a novel feature designed for ELAI in which different colouration codes for the different metals are applied, enabling a good regional allocation of a specific metal within the tissues. Chapter Four focuses on laser ablation processing of metallic and polymeric thin films used in microelectromechanical systems technology for the fabrication of microfluidic devices with integrated electrodes on printed circuit boards (PCB-MEMS). Chapter Five presents typical micro and nanotextured surfaces created by direct irradiation under stationary and non-stationary conditions and the mechanisms behind their development and growth are discussed. Chapter Six describes a novel three-dimensional (3-D) fabrication process of micro-scale shell resonator made of single-crystal diamond (SCD). Chapter Seven discusses the data about structural and morphological characteristics of nano-sized transition-metal oxides of zirconium and molybdenum produced by laser ablation in water.

Book SynopsisThe formation, deformation, and break-up of liquid interfaces are ubiquitous phenomena in nature. In the present book the authors discuss the deformation of a liquid interface produced by optical radiation forces. Usually, the bending of such an interface by the radiation pressure of a c.w. laser beam is weak. However, the effect can be enhanced significantly if one works with a near-critical phase-separated liquid mixture, whereby the surface tension becomes weak. The bending may in this way become as large as several tenths of micrometers, even with the use of only moderate laser power. This near-criticality is a key element in our experimental investigations as reviewed in the article. The effect is achieved by working with a micellar phase of microemulsions, at room temperature. The authors give a brief survey of the theory of electromagnetic forces on continuous matter, and survey earlier experiments in this area, such as the Ashkin-Dziedzic optical radiation force experiment on a water/air surface, the Zhang-Chang experiment on the laser-induced deformation of a micrometer-sized spherical water droplet, and the experiment of Sakai et al. measuring surface tensions of interfaces in a non-contact manner. Thereafter, the authors survey results they obtained in recent years by performing experiments on near-critical interfaces, such as interface bending in the linear regime, stationary large deformations of liquid interfaces, asymmetric pressure effects on interfaces under intense illumination, non-linear deformations, and laser-sustained liquid columns.

Book SynopsisThis book considers some general laser-induced processes that are involved in laser-matter interactions. A brief review is presented about a very interesting application of laser beams in the fields of materials science: the growth of zinc oxide (ZnO) nanostructured films by Pulsed Laser Deposition (PLD). In addition, safe and precise cavity detection, especially of dangerous or inaccessible voids, is essential to safe production in a working mine. The advantages and disadvantages of laser detection systems are analysed, and a combination of laser scanning techniques and conventional survey methodology is proposed. Other chapters in this book present an overview on laser cladding, a discussion of the applications of structured laser beams in laser refractography technology, a review of some fundamentals of laser-induced breakdown spectroscopy (LIBS) and an analysis of laser forming of steel parts by means of diode lasers.

Book SynopsisPulsed laser deposition (PLD) is at present one of the most interesting technique for thin film deposition. In the PLD process a film is formed by ablating a solid target with energetic laser pulses and collecting the material of interest on a substrate placed a few cm from the target. According to its ability to carry the stoichiometry from the target to the substrate and to its relatively high growth rate (~0.1 nm/pulse), PLD is an attractive technique for compound thin film deposition. This technique offers the possibility of depositing thin films on room-temperature or low-temperature substrates, due to the high energy of the species forming the laser plasma plume expanding from the target to the substrate. This book reviews research on the depositon of c-BN films by using PLD, ion-assisted PLD and other laser-assisted procedures.

Book SynopsisThis book studies the electrical, optical and structural properties of the Be-oped GaInas/AlGaAs multiple quantum-well structures (MQWs) at different doping density in the GaInls well, both designed and fabricated in house. The higher Be-doping density in the wells was found to enhance the compressive strain and increase barrier height of the GaInAs/AlGaAs MQWs through extensive optical characterisation. It caused the shifts of the sub-energy levels in the valence band of the well material and the absorption wavelength resulting from the intersubband absorption. These observations were verified by theoretical calculation based on the six-band Luttinger-Kohn model by taking the Be-doping into account.

Book SynopsisProductive direct conversion of lignocelluloses into liquid organic products by electron distillation of crude wood or by dry distillation of preliminarily irradiated wood is considered. Electron-beam conversion is several times more effective than ordinary hydrolytic, pyrogenous or enzymatic processing of wood. Distillation of wood by electron-beam energy yields a number of the useful reagents for heavy organic synthesis and fuel productions. In particular, this path results in high yield of furans -- perspective raw materials for production of high-quality alternative fuel which is compatible to conventional engine fuel and the up-to-date types of automobile engines. This book discusses that the electron-beam irradiation of binary wood-bitumen or wood-polymer inter-mixtures is characterised by sinergistic destruction of components.

Book SynopsisThis book presents new research related to femtosecond laser ablation, coherent control, electronic and thermal processes, colouring, nanoscale heat transfer, and corneal refractive surgery. With laser-pulse durations of one quadrillionth of a second, femtosecond lasers are poised to change the way research is done in a variety of disciplines in science, engineering and medicine. The ability to remove material with minimal collateral damage may be the most striking feature that has not been matched by any other material processing technologies. With the processing power carried by each pulse entering pettawatts (1015 W) in less than 100 femtoseconds, femtosecond lasers can remove virtually any type of material in a few picoseconds while confining the process zone to within tens of nanometers. The result is clean cuts, strong welds, and precision destruction of small targets such as cancer cells with no injury to surrounding materials.
