MASERS: A STATE-OF-THE ART SURVEY

A survey of masermicrowave amplification by stimulated emission of radiationtheory and technology is presented, to provide a basis whereby future maser potentialities may be determined. The study includes a brief historical sketch and an introduction to the theoretical concepts involved, a treatment of the various types of masers, their associated techniques and characteristics, a consideration of maser materials, operating parameters, and design limitations. It concludes with a discussion of present and future applications, particularly those relating to the program at USNUSL. An extensive bibliography is included. Author
