The maser is based on the principle of stimulated emission proposed by Einstein in 1917. When atoms have been induced into an excited energy state, they can amplify radiation at the proper frequency the most important type of maser is the hydrogen maser which is currently used as an atomic frequency standard . Together with other kinds of atomic clocks.
Norman Ramsey and his colleagues first conceived of the maser as a timing standard. More recent masers are practically identical to their original design. Maser oscillations rely on the stimulated emission …
