Available in PDF, EPUB and Kindle. Book excerpt: Optical phase conjugation, or time reversal, of an optical wave front is an important technique to correct distortions in electromagnetic waves which are built up during propagation through a medium. The authors have studied theoretically optical phase conjugation through four-wave mixing in a slab of non-linear material. When two strong counter-propagating laser beams irradiate a non-linear crystal, the third-order susceptibility is activated, and can couple to an external weak probe field. A four-wave mixing process then generates a phase-conjugated or time-reversed replica of this incident probe field. They investigated the mechanism of the production of phase-conjugated radiation in such a configuration by solving the non-linear Maxwell equations for the electric field. The electric field in the material satisfies a set of two coupled wave equations, which couple positive and negative frequency components of the electric field. It is shown that the polarisation of the pumps and the tensorial nature of the interaction can be accounted for by a simple polarisation operator in the wave equations. Maxwell's equations for the field in the layer admit plane-wave solutions, although the dispersion relations are very different from the usual linear relation between the frequency and the wave number. The coupling between the two waves exhibits a strong resonance near the frequency of the pump beams. These plane-wave modes can be matched across the boundaries of the layer to the probe field. The response of the material can then be expressed in terms of Fresnel reflection and transmission coefficients for both s- and p-polarisation. We have derived simple matrix equations for the set of Fresnel coefficients, which can be solved numerically, and the have also obtained closed-form analytical solutions for the various Fresnel coefficients. It is indicated that our solutions reduce to earlier results in the appropriate limits.

Book excerpt: This book is devoted to the classical and quantum phases in wave and particle optics from the viewpoint of both theory and applications. Wave and beam light optics are reviewed in considerable detail, featuring optical imaging and holography in linear optics and phase conjugation methods in nonlinear optics. Photon optics is embodied here as quantum optics with the modes treated as quantum harmonic oscillators. The importance of the Wigner function for the phase space description in the context of canonical quantization is respected and the method of quasidistributions related to operator orderings in the second-quantized theory is exposed. The history of the quantum phase problem, characterized by renewed interest in the solution to the problem, is included and brought up to date. Approaches based on exponential phase operators, discrete phase states, the enlargement of the Hilbert space of the harmonic oscillator leading to the phase representations and distributions, together with solutions motivated by the quasidistributions, are introduced. The operational approach to the quantum phase is contrasted with the previous formalisms. The results of the study of the coherent states and the ordinary squeezed states from the viewpoint of the quantum phase and those of the analysis of the quantum statistics of phase-related special states of the light field are provided. The quantum phase is also treated with respect to quantum interferometry, particle interferometry, nonlinear optical processes, and quantum nondemolition measurements.The book will prove indispensable to research workers in general optics, quantum optics and electronics, optoelectronics, and nonlinear optics, as well as to students of physics, optics, optoelectronics, photonics, and optical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This report results from a contract tasking Dynamic Holography Group, Institute of Physics. National Academy of Sciences as follows: The contractor will investigate getting the largest possible phase conjugate reflectivity in Sn2P2S6 by optimizing the usual parameters (such as pump intensity ratio, signal to pump intensity ratio, angle of incidence for pump and probe waves, polarization of interacting waves, orientation of waves with respect to sample principle axes) and frequency shift, a new parameter of special importance of Sn2P2S6. To achieve this the contractor shall perform the following: (1) The backward wave from four wave mixing will be used to generate the phase conjugate waves. Optimum conditions will be found to accomplish this. (2) Study different self-phase conjugate mirrors based on various coherent optical oscillators Optimize the performance of a double phase conjugating mirror. The study shows that SPS crystal can be efficiently used for conjugation of coherent light beams both in traditional backward-wave four-wave mixing geometry and in self-pumped coherent oscillator geometries. The samples belonging to Type I are suitable for conjugation both in the red (He-Ne laser light) and in near infrared (Nd(3+):YAG, 1.06 microns) while samples of Type II can be used for red and shorter infrared (0.8 ... 0.9 microns) region of spectrum. The phase conjugate intensity twice as large as the signal intensity was easily achieved in the red, at lambda = 0.63 microns. It is inevitable that with the same sample and the same refractive index modulation the phase conjugate reflectivity in infrared diminishes as lambda per 2 with the increasing lambda. This decrease can be compensated for by increasing the thickness of the samples used, what is essentially technological and not physical problem. With the available samples we got 17% phase conjugate reflectivity for Nd(3+):YAG, 1.06 microns radiation.

Available in PDF, EPUB and Kindle. Book excerpt: The Seventh Rochester Conference on Coherence and Quantum Optics was held on the campus of the University of Rochester during the four-day period June 7 - 10, 1996. More than 280 scientists from 33 countries participated. This book contains the Proceedings of the meeting. This Conference differed from the previous six in the series in having only a limited number of oral presentations, in order to avoid too many parallel sessions. Another new feature was the introduction of tutorial lectures. Most contributed papers were presented in poster sessions. The Conference was sponsored by the American Physical Society, by the Optical Society of America, by the International Union of Pure and Applied Physics and by the University of Rochester. We wish to express our appreciation to these organizations for their support and we especially extend our thanks to the International Union of Pure and Applied Physics for providing financial assistance to a number of speakers from Third World countries, to enable them to take part in the meeting.
