This book is concerned with the underlying science and design of laser materials. It emphasizes the principles of crystal-field engineering and discusses the basic physical concepts that determine laser gain and nonlinear frequency conversion in optical crystals. A concise review of the essential underlying science is presented, and the predictive capabilities of crystal-field engineering are developed to show how modification of the symmetry and composition of optical centres can improve laser performance. Applications of the principles of crystal-field engineering to a variety of optical crystals are also discussed in relation to the performances of laser devices. This book will be of considerable interest to physical, chemical and material scientists and to engineers involved in the science and technology of solid state lasers. It will be used by senior undergraduate and postgraduate students as well as by established scientists.

Strutural Analysis of Point Defects in Solids introduces theprinciples and techniques of modern electron paramagneticresonance (EPR) spectroscopy essentialfor applications tothe determination of microscopic defectstructures. Investigations of the microscopic and electronicstructure, and also correlations with themagnetic propertiesof solids, require various multiplemagnetic resonance methods, such as ENDOR and opticallydetected EPR or ENDOR. This book discusses experimental,technological and theoretical aspects of these techniquescomprehensively, from a practical viewpoint, with manyillustrative examples taken from semiconductors and othersolids. The nonspecialist is informed about the potential ofthe different methods, while the researcher faced with thetask of determining defect structures isprovided with thenecessary tools, together with much information oncomputer-aided methods of data analysis and the principlesof modern spectrometer design.
