Download or read book Optical Precursors written by Jiefei Chen and published by Springer Science & Business Media. This book was released on 2013-07-13 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since Einstein’s special relativity in 1905, the principle of invariant light speed in vacuum has been attracting attention from a wide range of disciplines. How to interpret the principle of light speed? Is light referred to continuous light, or light pulse with definite boundaries? Recent discovery of superluminal medium triggered vigorous discussion within the Physics community. Can communication via such “superluminal channel” break the speed limit and thus violate causality principle? Or, will a single photon, which is not governed by classical laws of Physics, tend to break the speed limit? To solve these problems, this Brief brings in Optical Precursors, the theoretical works for which started as early as 1914. This is a typical optical phenomenon combining wave propagation theory and light-wave interaction. Both theory and experimental works are covered in this Brief. The study of precursor verifies that the effective information carried by light pulses can never exceed the speed of light in vacuum- c. Further, through observation from nonclassical single photon source, the precursor rules out the probability of a single photon traveling with the speed, breaking the classical limit.

Book excerpt: Controlling and understanding the propagation of optical pulses through dispersive media forms the basis for optical communication, medical imaging, and other modern technological advances. Integral to this control and understanding is the ability to describe the transients which occur immediately after the onset of a signal. This thesis examines the transients of such a system when a unit step function is applied.
Download or read book Optical Precursors in Rubidium Vapor and Their Relation to Superradiance written by Wenlong Yang and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical precursor is the sharp optical pulse front that does not show delay in absorptive media. In this thesis, optical precursor behavior in rubidium (Rb) vapor was investigated in the picoseconds regime. An amplified femtosecond laser was shaped to a 7-ps square pulse with sharp rising and trailing edges. This pulse was then sent into a hot rubidium vapor, and the center frequency of the laser pulse was absorbed. The output pulses were measured by a fast streak camera with 2-picosecond resolution. By varying the temperature of the Rb vapor, the measured pulse shapes showed the progression of formation of optical precursors. The measured pulses shapes showed good agreement with theory. On the other hand, a connection between optical precursors and femtosecond laser pumped 3-photon superradiance was investigated in this thesis. Maxwell-Bloch equations were numerically solved in two steps with commercial software Mathematica 8. A good agreement was found between simulation and experiment. It was confirmed that, at low excitation regime, superradiance generated from hot rubidium vapor, which were pumped by a femtosecond laser, can be understood as the formation of optical precursors.

Download or read book Fiber Lasers written by Liang Dong and published by CRC Press. This book was released on 2016-09-19 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous development in the past decade or so, transforming itself from a research curiosity to a major force in modern manufacturing. Today, it is revolutionizing our economy by fundamentally changing the way we mark, machine, and process materials on an industrial scale. The recent development of high-power fiber lasers is also fundamentally shaping a wide range of other areas from physical sciences and medicine to geology and space exploration. In the past few years, the tactical deployment of direct energy weapons based on fiber lasers has become a reality. The development of fiber lasers is rooted in a number of technical areas including optical materials, optical waveguide design, nonlinear optics, optical fiber fabrication, and optical characterization, in addition to optical fiber components, and fiber laser design and architecture. No comprehensive in-depth coverage of such diverse topical areas has appeared in a single book. Many important developments have taken place in the past decade in both academia and industry. This book comprehensively covers the basics, technology and applications of fiber lasers including up-to-date developments in both academia and industry and is aimed to serve as both an introduction and research aid for graduate students, engineers, and scientists who are new to this field and also for veterans in the field
Download or read book Nanomaterials via Single Source Precursors written by Allen W. Apblett and published by Elsevier. This book was released on 2022-02-19 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nanoparticles, thin films and composites are described by a collection of international experts. Given the ability to customize the phase, morphology, and properties of target materials, this "rational approach to synthesis and processing is a disruptive technology for electronic, energy, structural and biomedical (nano)materials and devices. The use of single-source chemical precursors for materials processing technology allows for intimate elemental mixing and hence production of complex materials at temperatures well below traditional physical methods and those involving direct combination of elements. The use of lower temperatures enables thin-film deposition on lightweight polymer substrates and reduces damage to complex devices structures such as used in power, electronics and sensors. - Discusses new approaches to synthesis or single-source precursors (SSPs) and the concept of rational design of materials - Includes materials processing of SSPs in the design of new materials and novel devices - Provides comprehensive coverage of the subject (materials science and chemistry) as related to SSPs and the range of potential applications

Available in PDF, EPUB and Kindle. Book excerpt: Water is an indispensable resource for our society. Essential to sustaining life and economic prosperity, water is also the basic component for manufacturing almost everything to keep society alive, including energy, food, clothing, cars, and electronics, among many other examples. It is, thus, an integral part of our lives beyond simply quenching our thirst. In addition, our future economy and security highly depend upon the availability of clean water. Yet given its critical importance, there is a limited supply of renewable freshwater across the globe and there is no substitute. Global population and economic growth, urbanization, and climate change further exacerbate the increasing stress on freshwater supplies. As such, society urgently needs to find the scientific and engineering solutions to more efficiently manage our precious water resources. The volumes of this multi-volume reference cover the latest scientific advancements and solutions in managing and treating this crucial resource.Related Link(s)

Available in PDF, EPUB and Kindle. Book excerpt: While the asymptotic theory explains qualitatively my observations, I find that there are large quantitative disagreements. I hypothesize that these errors are due to the fact that I use a weakly-dispersive narrow-resonance medium for which this theory has never been tested. I suggest empirical fixes to the theory by comparison to my data. I also compare the asymptotic theory and data to a second theory that is known to describe well my experimental conditions, but was believed by some researchers not to predict optical precursors. I demonstrate that this belief is incorrect.
