Claim 0:
1. A laser frequency stabilization process comprising:
generating, using an optical frequency comb as a source of plural laser frequencies, laser beams, the laser beams including an output beam having a system output frequency, a first feedback beam having a first feedback frequency, and a second feedback beam having a second feedback frequency;
directing the first and second feedback beams respectively to first and second references to respectively yield first and second reference outputs, the first and second references respectively including quantum particles having respective quantum transition frequencies, the first and second reference outputs respectively representing a degree to which the first and second feedback frequencies match the quantum transition frequencies of the quantum particles respectively included by the first and second references, wherein the first reference has lower long-term stability than the second reference, and the second reference has lower short-term stability than the first reference; and
stabilizing the system output frequency based on the first and second reference outputs.
