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