Laser Beam Propagation Through Random Media available in PDF, EPUB and Kindle. Since publication of the first edition of this text in 1998, there have been several new, important developments in the theory of beam wave propagation through a random medium, which have been incorporated into this second edition. Also new to this edition are models for the scintillation index under moderate-to-strong irradiance fluctuations; models for aperture averaging based on ABCD ray matrices; beam wander and its effects on scintillation; theory of partial coherence of the source; models of rough targets for ladar applications; phase fluctuations; analysis of other beam shapes; plus expanded analysis of free-space optical communication systems and imaging systems.

Laser Beam Propagation in Random Media available in PDF, EPUB and Kindle. "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"--

Download and read online ebook Laser Beam Propagation in Nonlinear Optical Media write by Shekhar Guha. This book was released on 2017-12-19. Laser Beam Propagation in Nonlinear Optical Media available in PDF, EPUB and Kindle. "This is very unique and promises to be an extremely useful guide to a host of workers in the field. They have given a generalized presentation likely to cover most if not all situations to be encountered in the laboratory, yet also highlight several specific examples that clearly illustrate the methods. They have provided an admirable contribution to the community. If someone makes their living by designing lasers, optical parametric oscillators or other devices employing nonlinear crystals, or designing experiments incorporating laser beam propagation through linear or nonlinear media, then this book will be a welcome addition to their bookshelf." —Richard Sutherland, Mount Vernon Nazarene University, Ohio, USA Laser Beam Propagation in Nonlinear Optical Media provides a collection of expressions, equations, formulas, and derivations used in calculating laser beam propagation through linear and nonlinear media which are useful for predicting experimental results. The authors address light propagation in anisotropic media, oscillation directions of the electric field and displacement vectors, the walk-off angles between the Poynting and propagation vectors, and effective values of the d coefficient for biaxial, uniaxial, and isotropic crystals. They delve into solutions of the coupled three wave mixing equations for various nonlinear optical processes, including quasi-phase matching and optical parametric oscillation, and discuss focusing effects and numerical techniques used for beam propagation analysis in nonlinear media, and phase retrieval technique. The book also includes examples of MATLAB and FORTRAN computer programs for numerical evaluations. An ideal resource for students taking graduate level courses in nonlinear optics, Laser Beam Propagation in Nonlinear Optical Media can also be used as a reference for practicing professionals.

Download and read online ebook Laser Beam Propagation write by Andrew Forbes. This book was released on 2014-02-14. Laser Beam Propagation available in PDF, EPUB and Kindle. How do laser beams propagate? Innovative discoveries involving laser beams and their propagation properties are at the heart of Laser Beam Propagation: Generation and Propagation of Customized Light. This book captures the essence of laser beam propagation. Divided into three parts, it explores the fundamentals of how laser beams propagate, and provides novel methods to describe and characterize general laser beams. Part one covers the physical optics approach to the propagation of optical waves, the concept of plane waves, the mathematical description of diffraction and Gaussian optics, and adapting the concepts to the single photon level. The book explains the parallels between the paraxial propagation of light beams and the Schrödinger equation in quantum mechanics, and delves into the description of paraxial optics by means of state vectors and operators. It also discusses classical optics and quantum entanglement. Part two focuses on the application of modal decomposition to the characterization of laser beams, and provides a characterization of time domain pulses. It discusses tools for the temporal characterization of laser beams, the generation of arbitrary laser beams with digital holograms, and the use of spatial light modulators to display reconfigurable digital holograms capable of modifying and shaping laser beams. It also covers various techniques and the control of the polarization properties of light. Part three defines the most commonly generated shaped light, flat-top beams, outlining their propagation rules as well as the means to create them in the laboratory. It also highlights Helmholtz-Gauss beams, vector beams, and low coherence laser beams. The text presents the concepts of coherence theory and applies this to the propagation of low coherence optical fields. It also considers the recent developments in orbital angular momentum carrying fields, touches on basics properties, definitions and applications, and brings together the classical and quantum concepts of spatial modes of light.
