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 controlcontrolValerie Kuehne Undergraduate Research Awards (VKURA)Positive Reinforcement for Lasers: The Dichroic Atomic Vapour Laser LockPosterDepartment of Physics and Astronomy
