Abstract :
Absolute frequencies of an acetylene-stabilized laser at 1542 nm and an iodine-stabilized Nd:YAG at 1319 nm are measured at their second harmonics by use of a femtosecond optical comb based on a mode-locked Ti:sapphire laser. A frequency measurement system based on a mode-locked fiber laser (1.56mum) is also being developed for metrological applications in the telecommunication bands
