Abstract
We obtained fline = (351, 721, 960, 559 39) kHz, kappa = 1, as the absolute frequency of F = 4 rarr F´ = 5 transition of cesium D2 line by measuring the frequency of an external cavity diode laser (ECDL) locked to the center of the line with frequency modulation transfer technique. The frequency of ECDL was measured by an optical frequency synthesizer based on a 1-GHz femtosecond laser system linked to the hydrogen maser. To increase the S/N ratio of the beat note signal, a distributed Bragg reflector laser was injection locked to one of the optical comb components
