Paper Abstract

We report the results of a novel method for frequency-tracking and locking of the diode laser using the transmission spectrum of a Faraday anomalous dispersion optical filter (FADOF) as our frequency discriminator. A frequency stability of better than 2.1 X 10-10 for 100 ms <EQ (tau) <EQ 10 s was obtained, and continuous frequency scans of more than 2 GHz were made by changing the intensity of the magnetic field of the FADOF from 70 G to 220 G.
