By utilizing the Zeeman splitting of doppler-broadened atomic resonances, the frequency of an external cavity diode laser is stabilized exactly to the resonant frequency of rubidium. Using a rubidium cell designed by a previous student researcher, a repeatable, effective and robust control loop is developed and refined. The effectiveness is quantified using the dual DAVLL setup presented by Kristan Corwin (1998), and the range of frequencies to which a laser can be locked is measured. It is shown that the DAVLL is an inexpensive laser stabilization scheme that rarely loses its lock point.enphysicslaserlaser stabilizationfrequency stabilizationfeedback controlcontrolPoster
