Y. Millerioux et al., TOWARDS AN ACCURATE FREQUENCY STANDARD AT LAMBDA=778NM USING A LASER-DIODE STABILIZED ON A HYPERFINE COMPONENT OF THE DOPPLER-FREE 2-PHOTONTRANSITIONS IN RUBIDIUM, Optics communications, 108(1-3), 1994, pp. 91-96
Two systems are built in which a commercially available GaAlAs laser d
iode is stabilized on a hyperfine component of the 5S1/2-5D(3/2,5/2) t
wo-photon transitions in rubidium at lambda = 778 nm (nu = 385 THz). S
ome preliminary metrological results are presented. The frequency repe
atability has been found to be of 200 Hz (5.2 parts in 10(13)) and a s
hort-term frequency stability of 3 X 10(-13)/square-root tau up to 200
0 s is currently obtained.
