Optical frequency standards and measurement
This paper celebrates the progress in optical frequency standards and measurement, won by the 40 years of dedicated work of world-wide teams working in frequency standards and frequency measurement. Amazingly, after this time interval, the field is now simply exploding with new measurements and major advances of convenience and precision, with the best fractional frequency stability and potenti...
متن کاملError Analysis, Design and Modeling of an Improved Heterodyne Nano-Displacement Interferometer
A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...
متن کاملOptical Frequency Standards and Measurements
We describe the performance characteristics and frequency measurements of two high-accuracy high-stability lasercooled atomic frequency standards. One is a 657-nm (456-THz) reference using magneto-optically trapped Ca atoms, and the other is a 282-nm (1064-THz) reference based on a single Hg ion confined in an RF-Paul trap. A femtosecond mode-locked laser combined with a nonlinear microstructur...
متن کاملDirect comparison of two cold-atom-based optical frequency standards by using a femtosecond-laser comb.
With a fiber-broadened, femtosecond-laser frequency comb, the 76-THz interval between two laser-cooled optical frequency standards was measured with a statistical uncertainty of 2x10(-13) in 5 s , to our knowledge the best short-term instability thus far reported for an optical frequency measurement. One standard is based on the calcium intercombination line at 657 nm, and the other, on the mer...
متن کاملReport of Time and Frequency Activities at NICT (2012-2015)
The National Institute of Information and Communications Technology (NICT), an incorporated administrative agency, was established in 2004 with its large part inherited from the Communications Research Laboratory (CRL). The activity of time and frequency standards is conducted within the Space-Time Standards Laboratory of the Applied Electromagnetic Research Institute, this group itself compris...
