Technology
The maser is based on the principle of stimulated emission proposed by Albert Einstein in 1917. When atoms have been induced into an excited energy state, they can amplify radiation at the proper frequency.
By putting such an amplifying medium in a resonant cavity, feedback is created that can produce coherent radiation.
