The NIST Optically Pumped Cesium Frequency Standard
The National Institute of Standards and Technology is developing an optically pumped, cesium-beam primary frequency standard. The design follows from an analysis of systematic errors found in cesium beam standards. The details of the design, performance of major subsystems, and preliminary tests of the standard are presented.
متن کاملOptically Pumped Cesium-beam Frequency Standard for Gps-i11
We describe an optically pumped cesium-beam frequency standard under development for deployment on the GPS-III satellite constellation. The objective of the project is to demonstrate the feasibility of a space quulifikd optically pumped cesium-beam frequency standard exhibiting a short-term stability of cry (r < 6 x f-ln with lifetime and reliability comparable to that of the current GPS-IIF ce...
متن کاملVelocity Distribution Measurement of an Optically Pumped Cesium Frequency Standard at the NRLM
The velocity distributions of the optically pumped Cs frequency standard are measured using the sf pulse excitation method. The results are shifted toward higher beam velocity than the Maxwellian distribution and suggest a dependence on vacuum pressure. The velocity distribution is not sensitive to the laser power for pumping and detection, if the power is more than a few mW. The second-order D...
متن کاملStudy of He Rabi nutations by optically-pumped cesium magnetometers
We describe a method for recording the Rabi nutation of nuclear spin polarized He by optically pumped cesium magnetometers. The measurement is performed by detecting the time-dependent magnetic field produced by the He magnetization. The observed signals are compared to theoretical models and the results are used to precisely trace the evolution of the magnetization. This procedure represents a...
متن کاملCompact extended cavity diode laser system for small optically pumped cesium beam frequency standards
A compact extended cavity diode laser (ECDL) system operating at 852 nm for small optically pumped cesium (Cs) beam frequency standards was reported. ECDL and a saturated absorption spectroscopy setup were all built in an aluminum box with dimension of 10 × 10 × 7 (cm). ECDL was based on a LittmanMetcaff configuration, whose free-running linewidth was less than 600 kHz. A digital automatic freq...
