Abstract :
Broadband absolute frequency synthesis of over 1.4 THz with a 10 GHz spacing is demonstrated for pulsed coherent lightwaves. It is based on the recirculation of a rectangular pulse around an amplified fiber-optic loop with a high-speed external phase modulator, an acousto-optic (AO) frequency shifter and a high-finesse Fabry-Perot etalon for spectral reshaping.
