Book excerpt: The Optical Propagation Tests Study has analyzed the effects of atmospheric turbulence on atmospheric laser links. Analyses have found that scintillation (beam breakup), beam spread and beam wander will preclude operation of a high data rate uplink at 1 Gbps with an average P sub E of 0. 000001 unless special techniques are utilized in the ground transmitter design. It is predicted that focusing the beam at or above the tropopause will reduce the scintillation effects sufficiently, and pointing the uplink beam along the instantaneous normal to a downlink wavefront of a beam which originates at the satellite transmitter (reciprocity tracking) will remove most of the wander effects. A number of possible experimental techniques, suitable for testing these predictions have been explored. The recommendation is to perform an experiment in May/June 1974 using a variable focus reciprocity tracking ground transceiver and a balloon-borne (altitude 100,000 feet) system that is a modification of that developed in the Balloon Atmospheric Propagation Experiment. This recommendation allows for full utilization of the techniques (and equipment) developed under the 405B Acquisition/Tracking Brassboard programs and will specify the design constraints for the ground station by June 30, 1974.
Book Synopsis Methodology Study: Infrared-Optical Propagation Investigation by : Freeman F. Hall
Download or read book Methodology Study: Infrared-Optical Propagation Investigation written by Freeman F. Hall and published by . This book was released on 1972 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation has evaluated the application of infrared-optical propagation data correction techniques to the US Army Electronic Proving Ground's engineering test program. Scope of the effort covered a CDC documentation survey of 1972-80 time frame infrared-optical systems, the determination of the pertinent infrared-optical system test parameters which can be affected by propagation conditions in the Fort Huachuca meteorological environment and the evaluation of existing propagation models and data correction methodology for application to engineering test programming and data analysis requirements. The report considers five classes of electro-optical systems and four standard atmospheric conditions characteristics of the Fort Huachuca, Arizona test area. The methodology required to compute expected system performance degradation is presented to include the results of computations for a range of typical operational modes for each of the classes of systems and the supporting computer programs required to calculate the contrast reduction.

Book Synopsis Laser Beam Propagation in Nonlinear Optical Media by : Shekhar Guha
Download or read book Laser Beam Propagation in Nonlinear Optical Media written by Shekhar Guha and published by CRC Press. This book was released on 2017-12-19 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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 or read book Light Propagation in Gain Media written by Malin Premaratne and published by Cambridge University Press. This book was released on 2011-02-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, optical amplifiers have become of key importance in modern communications. In addition to this, the technology has applications in cutting-edge research such as biophotonics and lab-on-a-chip devices. This book provides a comprehensive treatment of the fundamental concepts, theory and analytical techniques behind the modern optical amplifier technology. The book covers all major optical amplification schemes in conventional materials, including the Raman and parametric gain processes. The final chapter is devoted to optical gain in metamaterials, a topic that has been attracting considerable attention in recent years. The authors emphasize analytical insights to give a deeper, more intuitive understanding of various amplification schemes. The book assumes background knowledge of electrical engineering or applied physics, including exposure to electrodynamics and wave motion, and is ideal for graduate students and researchers in physics, optics, bio-optics and communications.

Book Synopsis Review of Line of Sight Propagation Studies of the Small Scale Structure of the Atmosphere by : Stanford University. Stanford Electronics Laboratories
Download or read book Review of Line of Sight Propagation Studies of the Small Scale Structure of the Atmosphere written by Stanford University. Stanford Electronics Laboratories and published by . This book was released on 1969 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present state of theory and experiment are reviewed. Theory is adequate for line-of-sight propagation in weakly inhomogeneous media, and treats a wide variety of situations with potential for the probing of small-scale atmospheric phenomena, using acoustic, microwave and optical transmission. Thus far experiments have served mainly as tests of theory; useful information about the atmosphere will follow upon more intensive concern with the interpretive aspects of the problem. (Author).
