Elimination of quantum noise in the beat note of a laser

Spontaneous decay into the two modes of circular polarization of a Zeeman laser is correlated by radio-frequency coupling the Zeeman sublevels of the emitting atoms. No quantum noise is left over in the beat note of the polarization modes, at the centres of the ranges of frequency locking, when the...

Zusammenfassung:	Spontaneous decay into the two modes of circular polarization of a Zeeman laser is correlated by radio-frequency coupling the Zeeman sublevels of the emitting atoms. No quantum noise is left over in the beat note of the polarization modes, at the centres of the ranges of frequency locking, when the degeneracy of these modes is lifted by the pulling effect of linear dispersion.
