Abstract :
In this paper, we consider an optical frequency standard offering three simultaneous frequencies at 193, 385 and 578 THz, based on a two-photon transition in rubidium and sum-frequency generation in a periodically poled lithium niobate. Also, we give the theoretical evaluation and measurements of systematic effects shifting the frequency of this standard.
