This book was released on 1994 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This effort was a research program to investigate the (coherent and incoherent) nonlinear optical properties as a function of color centers. The investigation included multiwave mixing (four wave mixing and phase conjugation), spectral, and electron paramagnetic resonance properties of gamma-ray induced color centers. Investigations on BaTiO3 include EPR measurement parametric dependence of energy transfer for two coherent beams, influence of Fe and Cu impurities on the origin of photorefractive effects, resonance phase conjugation, and other beam coupling. SBN and BSO were studied. (MM).

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the processes of optical information recording in photorefractive crystals and applications of these materials in phase-conjugating devices, holographic interferometry, optical computers and sensors. It is in essence an extensive introduction to this new and rapidly developing area of quantum electronics. It presents physical concepts, fundamentals of theory, and important experimental data. A rigorous treatment of basic phenomena is accompanied by a quantitative analysis, which makes the book interesting to experts and accessible for newcomers to the field. Of particular interest to researchers is an extensive summary of basic physical and holographic parameters of all presently known photorefractive crystals and structures and also a detailed critical analysis of their applications.
Download or read book Studies of Optical Beam Phase Conjugation by Nonlinear Refraction written by R. W. Hellwarth and published by . This book was released on 1981 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: We demonstrated the first cw phase-conjugating mirror with gain, and made a self-oscillating resonator which emitted a diffraction-limited optical beam while severe phase aberration was present in the resonator. We demonstrated storable and erasable phase-conjugate images in the nanosecond regime by a one-photon photorefractive process. We achieved the first demonstration of a wide angle (approx. 45 deg.) narrowband approx. 1/10 cm) optical filter using phase conjugation. We achieved the first demonstration of full vector-wave phase-conjugation by which an image was restored after double-passing a birefringent phase aberrator. We demonstrated edge-enhancement of an optical phase-conjugate image in real time. Studies of resonant nonlinear refraction and phase conjugation in sodium vapor continued. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The photorefractive crystal barium titanate has been studied for its inherent physical properties and for its applications, including the locking together of separate laser beams. The output beams of two separate argon-ion lasers were locked together to within less than one Hz for an indefinite time. The technique uses four-wave mixing in the barium titanate crystal. A ring self-pumped phase conjugator was altered by inserting a nonreciprocal phase element in the ring so as to break its time-reversal symmetry. The device could be made to produce controlled frequency shifts and new output modes. Applications of this device are in mode conversion for optical computing. A transient detection microscope was invented which displays the images of moving objects, and which removes the stationary background. This all-optical device uses two-wave mixing in a barium titanate crystal. Keywords: Phase conjugation; Lasers; Photorefraction Barium titanate; Optical computing. (jhd).

Book excerpt: The purpose of this program has been the study, both theoretically and experimentally, of the use of phase conjugate optics for information processing and image transmission applications. A significant portion of effort was directed toward an improved understanding of the photorefractive effort and its application to two-wave and four-wave mixing. The authors developed a model for grating formation in photorefractive materials and have derived expressions for figures of merit, which aid in selection of materials and the optimization of efficiency and speed. They also developed a model for two-wave mixing in the transient regime, and measured response times for both tow-wave and four-wave mixing. Other devices and materials considered for ODP applications include the Hughes liquid crystal light valve and long-chain organic molecules. Measurements on several ODP configurations were performed. First, they used optical phase conjugation to transmit an image through a 1.75 m multimode fiber, with a resolution of better than 15 lines/mm. Secondly, they demonstrated several static convolution and correlation operations, using character masks. Finally, they investigated the use of phase conjugation for real-time optical correlation. Results of each of these experiments are described. (Author).

This book was released on 2013-11-27 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The photorefractive effect is now firmly established as one of the highest-sensitivity nonlinear optical effects, making it an attractive choice for use in many optical holographic processing applications. As with all technologies based on advanced materials, the rate of progress in the development of photorefractive applications has been principally limited by the rate at which breakthroughs in materials science have supplied better photorefractive materials. The last ten years have seen an upsurge of interest in photorefractive applications because of several advances in the synthesis and growth of new and sensitive materials. This book is a collection of many of the most important recent developments in photorefractive effects and materials. The introductory chapter, which provides the necessary tools for understanding a wide variety of photorefractive phenomena, is followed by seven contributed chapters that offer views of the state-of-the-art in several different material systems. The second chapter represents the most detailed study to date on the growth and photorefractive performance of BaTi03, one of the most important photorefractive ferroelectrlcs. The third chapter describes the process of permanently fixing holographic gratings in ferroelectrics, important for volumetric data storage with ultra-high data densities. The fourth chapter describes the discovery and theory of photorefractive spatial solitons. Photorefractive polymers are an exciting new class of photo refractive materials, described in the fifth chapter. Polymers have many advantages, primarily related to fabrication, that could promise a breakthrough to the marketplace because of ease and low-cost of manufacturing.
