Abstract :
We present our recent results toward the realization of an absolute frequency standard at 1556 nm based on the two-photon transition in rubidium at 778 nm. A compact transportable absolute frequency standard is described. Emphasis is put on the design of a periodically poled lithium niobate waveguide for efficient second-harmonic generation.
