METHOD OF TUNING THE OSCILLATION FREQUENCY OF THE RESONANT CAVITY OF A MASER OSCILLATOR TO THE TRANSITION FREQUENCY OF STIMULATED EMISSION OF THE ACTIVE MEDIUM OF SAID MASER

摘要

The method consists in periodically modulating the level of oscillation of the maser ; in detecting the phase variation of the maser oscillation with respect to the oscillation of a reference oscillator, namely the variation which takes place only in the event of mismatch of the resonant cavity of the maser and results from the modulation ; and in correcting the mismatch.
