The book "Solid-State Laser Engineering" by Walter Koechner, published by Springer Science+Business Media in 1976, is a comprehensive guide to the design, construction, and practical applications of solid-state lasers. The author, an industrial expert, emphasizes the engineering and practical aspects of solid-state laser technology, which has matured significantly over the past decade. The book covers fundamental concepts, major subsystems such as active materials, optical resonators, pump systems, and heat removal systems. It also discusses laser oscillators and amplifiers, devices that alter laser output, and system designs. The content is divided into chapters that provide detailed technical information, practical data, and references. The book is aimed at practicing scientists and engineers interested in solid-state laser technology and can also serve as a supplementary resource for students of laser physics. The author includes numerical and technical data, tables, and curves to enhance the practical understanding of laser construction and operation. The book is dedicated to the author's wife, Rea, for her support and encouragement.The book "Solid-State Laser Engineering" by Walter Koechner, published by Springer Science+Business Media in 1976, is a comprehensive guide to the design, construction, and practical applications of solid-state lasers.
