Fundamentals Of Optical Parametric Processes And Oscillations

This monograph outlines the basic theory of optical parametric processes and presents discussions on materials and practical device considerations. It emphasizes on optical parametric oscillators and mainly focuses on the three-photon parametric process.

This study looks at the basic principles of optical parametric processes and recent results on the rapidly developing optical parametric device technology. The theoretical basis of stimulated and spontaneous optical parametric processes and detailed design considerations of optical parametric oscillators and amplifiers are discussed, followed by a review of the materials properties of the most important nonlinear optical crystals for such applications. It concludes with a review of the recent developments on practical low-repetition rate nanosecond optical parametric oscillators and broadly tunable high-repetition rate continuous-pulse-train femtosecond optical parametric oscillations from the uv to the mid ir.

Nonlinear Optical Parametric Processes in Liquids and Gases focuses on the parametric processes that occur in liquids and gases. This book examines the mathematical results that are intended mainly for their usefulness in quantifying the physical interpretations of the various concepts to actual systems. Comprised of six chapters, this text starts with a discussion on the nonlinear optical processes, and then explores the basis for nonlinear optical interactions. This book describes the various third-order frequency mixing processes and the basic properties of nonlinear interactions, including phase matching and resonant enhancement. Other chapters consider the processes of frequency mixing and harmonic generation that are used as illustrations of the basic principles. The final chapter explores the applications of several nonlinear optical interactions, with a focus on the use of nonlinear optical processes to control the propagation of optical waves or to obtain information about a material system. This book is intended for researchers and readers engaged in the study of university-level mathematics, electromagnetic theory, and atomic physics.

This book provides researchers at the forefront of nonlinear optical technologies with robust procedures and software for the systematic investigation of the fundamental phenomena in nonlinear optical waveguide structures. A full vectorial electromagnetic formulation is adopted and the conditions under which simplification to a scalar formulation is possible are clearly indicated. The need to model the dielectric saturation properly is identified, and improved algorithms are presented for obtaining the complete power dispersion curve of structures exhibiting bistability. As the stability analysis of nonlinear modes is crucial to the development of nonlinear model methods, an effective procedure to investigate the propagation of the scalar nonlinear waves in 3D is another important feature of the book. All of the procedures described, as well as an automatic mesh generator for the finite element method, are incorporated into a software package which is included with this book.

This volume considers optical parametric generation and amplification (OPG/OPA), as a means for producing a tunable optical parametric device. It reviews the OPA/OPG systems using various crystals pumped by lasers at various frequencies with pulse duration ranging from picoseconds to femtoseconds. Part two covers the theoretical background for design of an OPA/OPG system, using two newly discovered nonlinear crystals. Experimental design considerations are discussed in section three, including the section of nonlinear crystals, pumping sources and optical configurations. In section four, the experimental results obtained are compared with the theoretical calculations.

This book reviews basic electromagnetic (EM) wave theory and applies it specifically to lasers in order to give the reader not only tangible examples of how the theory is manifested in real life, but also practical knowledge about lasers, and their operation and usage. The latter can be useful for those involved with using lasers. As a short treatise on this subject matter, this book is not intended to dwell deeply into the details of EM waves nor lasers. A bibliography is provided for those who wish to explore in more depth the topics covered in this book. Rather the aim of this book is to offer a quick overview, which will allow the reader to gain a competent general understanding of EM waves and lasers.
