Many of the Air Force Research Laboratory’s experimental efforts are focused on precision navigation and timing. The establishment and testing of an optical frequency standard is useful for numerous terrestrial and space based applications. Therefore, an optical atomic clock based upon a 778 nm two-photon transition in rubidium, is an excellent candidate to meet GPS-III frequency stability requirements, as commercial off-the-shelf components allow for a simple set-up that supports 7 x 10^-13 at 1 second.
