maser amplifier

(may -zer) A type of negative-resistance amplifier in which amplification is achieved by stimulating excited molecules to release photons in phase with the passing radiation. Amplifiers of this type have extremely low noise figures, limited in practice by losses in the input and output circuits, and they therefore find application in radio telescopes at microwave frequencies.
