Stabilizing Lasers by Analyzing Phase Noise
External cavity diode lasers mode hop unexpectedly and often. Based on previous measurements by others in the field, we have theorized that a substantial amount of phase noise occurs when a laser is about to switch modes. By monitoring this phase noise and making necessary adjustments, laser stability could possibly be maintained. We have developed an experiment to measure the phase noise to test our theory and determine the feasibility of this stabilization technique.
