The Springer Series in Optical Sciences includes a collection of books on various topics in optics and photonics. The series features a range of volumes, including "Principles of Phase Conjugation," "X-Ray Microscopy," "Introduction to Laser Physics," "Scanning Electron Microscopy," "Holography and Deformation Analysis," "Tunable Solid State Lasers," "Integrated Optics," "Laser Spectroscopy," "Laser-Induced Dynamic Gratings," and others. Each volume is edited by experts in the field and covers different aspects of optical science and technology. The series also includes a handbook on nonlinear optical crystals, which is the focus of this summary. The handbook, titled "Handbook of Nonlinear Optical Crystals," is in its third revised edition and provides a comprehensive overview of nonlinear optical crystals, their properties, and applications. It includes detailed information on various types of nonlinear optical crystals, such as BBO, LBO, KTP, ZnGeP2, and others. The book also discusses the theory of nonlinear frequency conversion, phase-matching conditions, and the practical applications of nonlinear optical crystals in laser physics and quantum electronics. The handbook is edited by three prominent scientists: V. G. Dmitriev, G. G. Gurzadyan, and D. N. Nikogosyan. The book is intended for specialists and practitioners with an engineering background and includes a list of commonly used laser wavelengths in the appendix. The handbook is a valuable resource for researchers and professionals in the field of nonlinear optics and optical materials.The Springer Series in Optical Sciences includes a collection of books on various topics in optics and photonics.
