Book excerpt: This book delves deeply into the real-world technologies behind the ‘directed energy weapons’ that many believe exist only within the confines of science fiction. On the contrary, directed energy weapons such as high energy lasers are very real, and this book provides a crash course in all the physical and mathematical concepts that make these weapons a reality. Written to serve both scientists researching the physical phenomena of laser effects, as well as engineers focusing on practical applications, the author provides worked examples demonstrating issues such as how to solve for heat diffusion equation for different boundary and initial conditions. Several sections are devoted to reviewing and dealing with solutions of diffusion equations utilizing the aid of the integral transform techniques. Ultimately this book examines the state-of-the-art in currently available high energy laser technologies, and suggests future directions for accelerating practical applications in the field.“br>/div

This book was released on 2018-01-31 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laser has revolutionized many areas of science and society, providing bright and versatile light sources that transform the ways we investigate science and enables trillions of dollars of commerce. Now a second laser revolution is underway with pulsed petawatt-class lasers (1 petawatt: 1 million billion watts) that deliver nearly 100 times the total world's power concentrated into a pulse that lasts less than one-trillionth of a second. Such light sources create unique, extreme laboratory conditions that can accelerate and collide intense beams of elementary particles, drive nuclear reactions, heat matter to conditions found in stars, or even create matter out of the empty vacuum. These powerful lasers came largely from U.S. engineering, and the science and technology opportunities they enable were discussed in several previous National Academies' reports. Based on these advances, the principal research funding agencies in Europe and Asia began in the last decade to invest heavily in new facilities that will employ these high-intensity lasers for fundamental and applied science. No similar programs exist in the United States. Opportunities in Intense Ultrafast Lasers assesses the opportunities and recommends a path forward for possible U.S. investments in this area of science.

Available in PDF, EPUB and Kindle. Book excerpt: Directed Energy Weapons is nothing new to mankind, historically the origination of such weapons falls in centuries ago when first time the famous Greek mathematician, physicist, engineer, inventor, and astronomer Archimedes of Syracuse used different mirrors to collect sunbeams and focusing them on Romans fleet in order to destroy enemy ships with fire. This is known as the Archimedes Heat Ray. Archimedes may have used mirrors acting collectively as a parabolic reflector to burn ships attacking Syracuse. The device was used to focus sunlight onto approaching ships, causing them to catch fire. Of course the myth or reality of Archimedes Heat Ray still is a questionable story, but certain experiments with the help of a group of students from Massachusetts Institute of Technology was carried out with 127 one-foot (30 cm) square mirror tiles in October of 2005 that was focused on a mock-up wooden ship at a range of around 100 feet (30 m). The flames broke out on a patch of the ship, but only after the sky had been cloudless and the ship had remained stationary for around ten minutes. It was concluded the device was a feasible weapon under these conditions.

This book was released on 2013-09-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U. S. Air force currently invests significantly in science and technology for directed-energy weapon (DEW) systems. Key elements of this investment include high-energy lasers and high-power microwaves. Other DEW research and development efforts include: optical beam control for high-energy lasers; vulnerability and lethality assessments; and advanced non-conventional and innovative weapons. Selected Directed Energy Research and Development for U.S. Air Force Aircraft Applications is the summary of three workshop sessions convened between February and April, 2013 by the Air Force Studies Board of the National Academies' National Research Council. Representatives from the Air Force science and technology community and DEW experts from the U.S. Army, U.S. Navy, Office of the Secretary of Defense, and the Defense Advanced Research Projects Agency presented and discussed threats that DEW capabilities might defend against and assessments of foreign progress in DEW. This report examines the current status of DEW capabilities both in the U.S. and abroad, and considers future applications of DEW systems.

This book was released on 2009-04-06 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a scientific assessment of free-electron-laser technology for naval applications. The charge from the Office of Naval Research was to assess whether the desired performance capabilities are achievable or whether fundamental limitations will prevent them from being realized. The present study identifies the highest-priority scientific and technical issues that must be resolved along the development path to achieve a megawatt-class free-electron laser. In accordance with the charge, the committee considered (and briefly describes) trade-offs between free-electron lasers and other types of lasers and weapon systems to show the advantages free-electron lasers offer over other types of systems for naval applications as well as their drawbacks. The primary advantages of free-electron lasers are associated with their energy delivery at the speed of light, selectable wavelength, and all-electric nature, while the trade-offs for free-electron lasers are their size, complexity, and relative robustness. Also, Despite the significant technical progress made in the development of high-average-power free-electron lasers, difficult technical challenges remain to be addressed in order to advance from present capability to megawatt-class power levels.

Download or read book High Power Optics written by Victor V. Apollonov and published by Springer. This book was released on 2014-11-21 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the basics, realization and materials for high power laser systems and high power radiation interaction with matter. The physical and technical fundamentals of high intensity laser optics and adaptive optics and the related physical processes in high intensity laser systems are explained. A main question discussed is: What is power optics? In what way is it different from ordinary optics widely used in cameras, motion-picture projectors, i.e., for everyday use? An undesirable consequence of the thermal deformation of optical elements and surfaces was discovered during studies of the interaction with powerful incident laser radiation. The requirements to the fabrication, performance and quality of optical elements employed within systems for most practical applications are also covered. The high-power laser performance is generally governed by the following: (i) the absorption of incident optical radiation (governed primarily by various absorption mechanisms), (ii) followed by a temperature increase and response governed primarily by thermal properties and (iii) the thermo-optical and thermo-mechanical response of distortion, stress, fracture, etc. All this needs to be understood to design efficient, compact, reliable and useful high power systems for many applications under a variety of operating conditions, pulsed, continuous wave and burst mode of varying duty cycles. The book gives an overview of an important spectrum of related topics like laser resonator configurations, intermetallic optical coatings, heat carriers for high power optics, cellular materials, high-repetition-rate lasers and mono-module disk lasers for high power optics.

Book excerpt: In the thirty years since the invention of the CO2 gas laser, the major design issue has shifted from how to obtain the desired power level to how to achieve reliable operation. At the same time, the opening of many laser development facilities in the Former Soviet Union has allowed their achievements and design approaches to be understood and appreciated for the first time. Further, the industrial laser user community has identified a number of emerging applications at higher power levels (15-20 kW) than are attainable by most commercial devices. In High Power Lasers - Science and Engineering, the designers, developers and users of high-power gas laser systems discuss design approaches, methods of enhancing performance, new applications, and user requirements.
