Nikolay Basov analyzed coherent molecular amplification with Alexander Prokhorov. Their 1956 maser theory relates the generated frequency to both the molecular transition and the cavity response, showing why a molecular oscillator can serve as a precise frequency reference. Below the condition for self-sustained oscillation, the same system can amplify an external microwave input. Distinguishing an amplifier from an oscillator therefore depends on feedback and loss as well as molecular excitation.[ref]
