Classification: CPC H  G | IPC G  H

Claim 10:
11. A laser stabilization system comprising:
an optical frequency comb that provides a laser system output beam having a laser-system output frequency, and plural feedback beams having respective feedback frequencies, the plural feedback beams having a first feedback beam having a first feedback frequency, a second feedback beam having a second feedback frequency;
a reference system having plural quantum references, the plural quantum references including first and second quantum references, the first quantum reference including a population of quantum particles having a first transition frequency, a second quantum reference including a population of quantum particles having a second transition frequency, the first and second quantum references being optically coupled to the optical frequency comb for respectively receiving the first and second feedback beams, the first and second quantum references respectively outputting a first and second reference outputs in response to receiving the first and second feedback beams, the first and second reference outputs respectively indicating respective extents to which the respective feedback frequencies match the respective transition frequencies; and
a controller for stabilizing the laser-system output frequency based on both of the first and second reference outputs.
