Ultra-Low Phase Noise Atomic Clock using Coherent.

This thesis describes the design and implementation of a complete atomic clock system from first principles. The system is based on Coherent Population Trapping (CPT) in 85Rb and incorporates an ultra-low phase noise multi-element local oscillator, consisting of a 10MHz crystal oscillator and 1.5GHz Dielectric Resonator Oscillator (DRO) in a phase locked configuration.

Towards a strontium optical lattice clock - ORA - Oxford.

Towards a strontium optical lattice clock Abstract: Due to the recent success, in terms of accuracy and precision, of a number of strontium optical lattice optical frequency standards, and the classification of the 5 s 2 1 S 0 to 5 s 5 p 3 P 0 transition in neutral strontium as a secondary definition of the SI unit of the second, many new strontium lattice clocks are under development.Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2011. For the past decade, the stability of microwave atomic clocks has stood at the standard quantum limit, set by the projection noise inherent in measurements on ensembles of uncorrelated particles.Ludlow, Andrew D. (Ph.D., Physics) The Strontium Optical Lattice Clock: Optical Spectroscopy with Sub-Hertz Accuracy Thesis directed by Assoc. Prof. Adjoint Jun Ye One of the most well-developed applications of coherent interaction with atoms is atomic frequency standards and clocks. Atomic clocks nd signi cant roles in a num-.


Title: Understanding atomic interactions in an optical lattice clock and using them to study many-body physics.This thesis presents the experimental scheme for a guided cold atom Sagnac interferometer. Although atom interferometers have become an established method for precision measurements, a feasible clock-scheme based on fully guided atoms has yet to be realised. Radio frequency potentials, generated by a chip, provide a means to create a compact, fully controllable guided atom interferometer.

An atomic clock is a clock device that uses a hyperfine transition frequency in the microwave, or electron transition frequency in the optical or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time.

Atomic Clock. Definition. Atomic clock is an extremely precise clock whose rate is controlled by a periodic process, such as vibration, or the absorption or emission of electromagnetic radiation that occurs at a steady rate in atoms or molecules. It is the most accurate type of timepiece in the world, designed to measure time according to.
