Abstract
The frequency of a diode laser system at 193 THz (1556 nm), which is freque ncy doubled and locked to a two-photon transition in rubidium at 385 THz (7 78 nm), has been measured with a Cs-based frequency chain and a single Sri ion standard at 445 THz. The output frequency of the diode laser system was measured to be 192 642 283 183 700 +/- 500 Hz. After applying corrections for systematic offsets in the rubidium spectrum, the frequency of the Rb-87 5S(1/2)(F-g = 2) - 5D(5/2)(F-e = 4) two-photon transition is found to be 3 85 284 566 370.4 +/- 2 kHz.
