Abstract
A novel optical interferometric technique is proposed for stabilizing and measuring a laser frequency in terms of an rf standard. In preliminary studies, a sensitive optical dual-frequency modulation scheme allows locking a laser to an optical cavity and the cavity in turn to a radio frequency reference with a noise level of 60 × Hz or 2 parts in . In principle, the laser frequency can acquire the stability of the rf standard and being locked to a high-order multiple of the rf frequency facilitates the optical-rf division .
