WebThe 4th edition of this classic text provides a thorough coverage of RF and microwave engineering concepts, starting from fundamental principles of electrical engineering, with applications to microwave circuits and … A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The first maser was built by Charles H. Townes, James P. Gordon, and Herbert J. Zeiger at Columbia University in 1953. Townes, Nikolay Basov and Alexander Prokhorov were awarded the … Ver más The theoretical principles governing the operation of a maser were first described by Joseph Weber of the University of Maryland, College Park at the Electron Tube Research Conference in June 1952 in Ver más Masers serve as high precision frequency references. These "atomic frequency standards" are one of the many forms of atomic clocks. … Ver más The meaning of the term maser has changed slightly since its introduction. Initially the acronym was universally given as "microwave amplification by stimulated emission of radiation", which described devices which emitted in the microwave region of the Ver más • List of laser types • Laser • X-ray laser • Gamma-ray laser (graser) • Sonic laser (saser) Ver más The maser is based on the principle of stimulated emission proposed by Albert Einstein in 1917.
