Book Description
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

Book Description
The whole story of laser weapons with a focus on its many interesting characters and sometimes bizarre schemes The laser--a milestone invention of the mid-twentieth century--quickly captured the imagination of the Pentagon as the key to the ultimate weapon. Veteran science writer Jeff Hecht tells the inside story of the adventures and misadventures of scientists and military strategists as they exerted Herculean though often futile efforts to adapt the laser for military uses. From the 1950s' sci-fi vision of the death ray, through the Reagan administration's Star Wars missile defense system, to more promising developments today, Hecht provides an entertaining history. As the author illustrates, there has always been a great deal of enthusiasm and false starts surrounding lasers. He describes a giant laser that filled a Boeing 747, lasers powered like rocket engines, plans for an orbiting fleet of robotic laser battle stations to destroy nuclear missiles, claims that nuclear bombs could produce intense X-ray laser beams, and a scheme to bounce laser beams off giant orbiting relay mirrors. Those far-out ideas remain science fiction. Meanwhile, in civilian sectors, the laser is already being successfully used in fiber optic cables, scanners, medical devices, and industrial cutting tools. Now those laser cutting tools are leading to a new generation of laser weapons that just might stop insurgent rockets. Replete with interesting characters, bizarre schemes, and wonderful inventions, this is a well-told tale about the evolution of technology and the reaches of human ambition.

Book Description
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.

Book Description
Physics of Optoelectronics focuses on the properties of optical fields and their interaction with matter. Understanding that lasers, LEDs, and photodetectors clearly exemplify this interaction, the author begins with an introduction to lasers, LEDs, and the rate equations, then describes the emission and detection processes. The book summarizes and reviews the mathematical background of the quantum theory embodied in the Hilbert space. These concepts highlight the abstract form of the linear algebra for vectors and operators, supplying the "pictures" that make the subject more intuitive. A chapter on dynamics includes a brief review of the formalism for discrete sets of particles and continuous media. It also covers the quantum theory necessary for the study of optical fields, transitions, and semiconductor gain. This volume supplements the description of lasers and LEDs by examining the fundamental nature of the light that these devices produce. It includes an analysis of quantized electromagnetic fields and illustrates inherent quantum noise in terms of Poisson and sub-Poisson statistics. It explains matter-light interaction in terms of time-dependent perturbation theory and Fermi's golden rule, and concludes with a detailed discussion of semiconductor emitters and detectors.

Book Description
The Cold War saw scientists in East and West racing to create amazing new technologies, the like of which the world had never seen. Yet not everyone was taken by surprise. From super-powerful atomic weapons to rockets and space travel, readers of science fiction (SF) had seen it all before. Sometimes reality lived up to the SF vision, at other times it didn’t. The hydrogen bomb was as terrifyingly destructive as anything in fiction, while real-world lasers didn't come close to the promise of the classic SF ray gun. Nevertheless, when the scientific Cold War culminated in the Strategic Defence Initiative of the 1980s, it was so science-fictional in its aspirations that the media dubbed it “Star Wars”. This entertaining account, offering a plethora of little known facts and insights from previously classified military projects, shows how the real-world science of the Cold War followed in the footsteps of SF – and how the two together changed our perception of both science and scientists, and paved the way to the world we live in today.
