Paper Abstract

Methods of precision laser spectroscopy and optical frequency synthesis are discussed in view of their application in optical frequency standards. The lowest possible uncertainty is expected from a standard based either on a single ion, trapped and laser cooled in a radio-frequency trap, or an ensemble of neutral atoms released from a magneto-optical trap. A relative frequency uncertainty of 2.5 (DOT) 10-13 has already been demonstrated for a Ca optical frequency standard using the latter concept. Aa novel method of optical frequency synthesis based on femtosecond lasers is also described.
