Professor Yurii A. Anan'ev has a long-standing international reputation for his publications on optical beams and resonators. Now many of his contributions will be readily available for the first time in a book. The generation of maximum power, minimum divergence beams from laser resonators is probably the most important topic in quantum electronics and optics today. The only book of its kind, Laser Resonators and the Beam Divergence Problem covers not only the theory, but also the applications of resonators to real systems as opposed to idealized models. Each rigorous examination of an optical configuration is accompanied by a detailed discussion of its associated applications and of the considerations for the user in practical work. The book contains a wealth of information on the developments in resonator technology, including much material previously unavailable outside the Soviet Union. It is an essential reference source to every researcher in laser science and technology.
