Abstract
A system for producing two or more laser beams having stable frequency differences between them. The system includes two or more lasers that produce the respective laser beams, an optical resonator, and coupling optics for coupling portions of each laser beam into the resonator. The resonator produces feedback beams that are returned to the respective lasers to provide optical feedback. The feedback causes each laser to lock to a resonant mode of the resonator, to thereby stabilize the frequency difference between the lasers. The linewidth of each laser is also reduced.
