Book Description
"This research monograph is a companion edition and update to the book: (AP) L. C. Andrews and R. L. Phillips, Laser Beam Propagation through Random Media, 2nd ed. (SPIE Press, WA, 2005). We present several new and advanced topics that have emerged during the years since (AP) 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 Description
From science fiction death rays to supermarket scanners, lasers have become deeply embedded in our daily lives and our culture. But in recent decades the standard laser beam has evolved into an array of more specialized light beams with a variety of strange and counterintuitive properties. Some of them have the ability to reconstruct themselves after disruption by an obstacle, while others can bend in complicated shapes or rotate like a corkscrew. These unusual optical effects open new and exciting possibilities for science and technology. For example, they make possible microscopic tractor beams that pull objects toward the source of the light, and they allow the trapping and manipulation of individual molecules to construct specially-tailored nanostructures for engineering or medical use. It has even been found that beams of light can produce lines of darkness that can be tied in knots. This book is an introductory survey of these specialized light beams and their scientific applications, at a level suitable for undergraduates with a basic knowledge of optics and quantum mechanics. It provides a unified treatment of the subject, collecting together in textbook form for the first time many topics currently found only in the original research literature.

Book Description
Random lasers are the simplest sources of lasers, since they exhibit stimulated emission without a cavity, with the feedback provided by scattering in a gain medium. First proposed in the late 60's, random lasers have grown into a large research field. This book reviews the history and the state of the art of random lasers, providing an outline of the basic models explaining their behavior and describing the recent advances in the field. The major focus is solid-state random lasers, however, random lasers based on liquid dyes with scatterers are also briefly treated. Written with mostly self-contained chapters, Solid-State Random Lasers gives scientists or engineers interested in a particular aspect directly access to the relevant information. Researchers entering the field of random lasers will find in the book an excellent overview, while scientists already working in the field can use the book as a reference source.
