Available in PDF, EPUB and Kindle. Book excerpt: We report the results of our theoretical study on the key physical processes that affect the propagation of nigh energy lasers in the atmosphere. The main objective of this study is to discuss the optimum laser wavelength and power for efficient propagation in maritime, desert, rural and urban atmospheric environments. The theoretical/numerical model used in this study includes the effects of aerosol and molecular scattering, aerosol heating and vaporization, thermal blooming due to aerosol and molecular absorption, atmospheric turbulence, and beam quality. These processes are modeled in a fully three-dimensional and time-dependent manner. It is found that aerosol particles are particularly important because they result in laser scattering, absorption and enhanced thermal blooming. In the water vapor transmission windows, the total absorption coefficient driving thermal blooming can be caused mainly by aerosols and not water vapor. In certain maritime environments the deleterious effects of aerosols can be reduced by vaporization. Aerosol particles which cannot be vaporized, such as those Consisting of dust, soot, etc., can significantly increase thermal blooming. The optimum wavelength and power for propagation are found for each atmospheric environment.

Download or read book Propagation of High-Energy Laser Beam in the Atmosphere written by Charles B. Hogge and published by . This book was released on 1974 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric turbulence can affect the propagation of laser beams of any power. Thermal blooming, a nonlinear propagation process, can seriously degrade high-energy beams. These two processes are reviewed in detail, with emphasis on parametric effects such as aperture size wavelength, and focal distance. Included in the discussion are such new topics as supersonic slewing and stagnation zone problems. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Various factors that can affect thermal blooming in stagnation zones are examined, including stagnation-zone motion, longitudinal air motion in the neighborhood of the stagnation zone, and the effects of scenario noncoplanarity. Of these effects, only the last offers any reasonable hope of reducing the strong thermal blooming that normally accompanies stagnation zones; in particular, noncoplanarity should benefit multipulse more than cw beams. The methods of treating nonhorizontal winds hydrodynamically for cw and multipulse steady-state sources are discussed. Pulse ''self-blooming'' in the triangular pulse approximation is discussed in the context of both single and multipulse propagation. It is shown that self-blooming and multipulse blooming cannot be treated independently.
Book Synopsis Laser Beam Propagation by : Andrew Forbes
Download or read book Laser Beam Propagation written by Andrew Forbes and published by CRC Press. This book was released on 2014-02-14 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Frontiers in High Energy Density Physics written by National Research Council and published by National Academies Press. This book was released on 2003-05-11 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.
