'Passive H maser'
Abstract
The present work describes a new improved technique for the passive H servo loops consisting in the use of a single modulation frequency and phase discrimination for the separation of the cavity and H line error signals. The cavity resonance is interrogated with the 'absorption lock' technique and the H resonance with the 'dispersion lock' technique. Preliminary measurements of the frequency stability obtained by comparison of two passive H masers are also reported.
