Volume 1: Solid-State Laser Engineering by W. Koechner. Volume 2: Table of Laser Lines in Gases and Vapors by R. Beck, W. Englisch, and K. Gürs. Walter Koechner is the author of Solid-State Laser Engineering, a book that provides a detailed discussion of solid-state lasers, their characteristics, design and construction, and practical problems. The title emphasizes the focus on engineering and practical considerations. The book is divided into several parts, with the first chapter introducing fundamental concepts. The major subsystems of a solid-state laser, including active material, optical resonator, pump system, and heat removal system, are discussed in subsequent chapters. Chapters 3 and 4 cover regenerative laser oscillator and amplifier, with results of analytical models expressed in practical, measurable quantities. Chapters 8, 9, and 10 describe devices that alter the output of a laser oscillator in time or frequency. Chapter 11 provides a description of system designs, including system and performance parameters of the most useful solid-state lasers. Chapter 12 contains practical information on the damage mechanism and damage level of optical components used in solid-state lasers. The two appendices contain information on laser safety and a summary of frequently used constants and conversion factors. The book is mainly directed to practicing scientists or engineers interested in the design or use of solid-state lasers. It is hoped that the comprehensive treatment of the subject makes the work useful also to students of laser physics who want to supplement their theoretical knowledge with the engineering aspects of lasers. Although not written in the form of a college textbook, the book might be used in an advanced college course on laser technology. The aim was to present the subject as clearly as possible, using phenomenological descriptions with models rather than abstract mathematical presentations. Results are given without proof, as the author tried to stress the application of the results rather than the derivation of the formulas. Pertinent references are cited for a detailed account. The book discusses only laser designs that have found practical applications. Many different devices, materials, components, and concepts were developed over the years. However, the lasers that have emerged after a dozen years of development and now dominate the laser market, though developed by different companies, are similar in design and construction. The author has tried to enhance the description of the engineering aspects of laser construction and operation by including numerical and technical data, tables, and curves. One area of special interest, laser applications, was initially intended to form a somewhat larger portion of the book. However, the appearance of several good books on this subject made a more extensive discussion of this field unnecessary. The author is indebted to Dr. M. Stitch and D. Smart for their careful reading of the manuscript and suggestions for corrections. A special note of gratitude goes to Rea Koechner and Margaret Lochart for typing the manuscript on a tight schedule. Thanks are due to the editor, Dr. H. LotsVolume 1: Solid-State Laser Engineering by W. Koechner. Volume 2: Table of Laser Lines in Gases and Vapors by R. Beck, W. Englisch, and K. Gürs.
