Abstract :
Describes an optical reference signal obtained by frequency locking a AlGaAs laser to the absorption spectrum of rubidium. The rubidium absorption spectrum is frequency-modulated by an AC magnetic field using the Zeeman effect. This technique results in an optical reference signal which is free from undesired modulation
