Optical pumping cesium beam tubes
WebPreliminary operation of the beam tube has been performed with a single laser narrowed by optical feedback and locked to the F = 4 + F' = 4 transition in a separate saturated absorption cell. This laser was used to drive the pumping zone with an optical power density of about 5 mW/cm2.

WebThe optical pumping efficiency has been characterized by two techniques: state-selective laser atom deflection or magnetic dephasing of the atom interferometer signals. sian chayWebJun 7, 2024 · Optically pumped cesium beam atomic clocks use two hyperfine levels of cesium atoms ( F = 3, m F = 0> and F = 4, m F = 0>. In order to separate the other magneton levels from the two levels, we add a weak magnetic field, called C field. So we can reduce the influence of other magneton transitions. sian chay donationWebA more symmetric beam reversal is possible with optical pumping methods, since all atoms may be included regardless of velocity and position within the beam. This should permit a better cancellation of cavity phase shifts. Angle tuning of the laser may result in velocity selection of atoms in the cesium beam, favoring slower velocity atoms, which sian chay branchesWebMay 1, 1991 · As a core device, the cesium beam tube which provides a high vacuum environment for the generation of atomic beams and the interaction of radiation fields with atoms is the most important... the pennypit community development trustWebDirect-Replacement Cesium Beam Tubes for 5071A Key Features Self-install or factory replacement options Extend lifespan of Primary Frequency Standard (PFS) High-performance and standard-performance options 5-year warranty for high-performance tubes 10-year warranty for standard-performance tubes sian channel 5 news readerWebKarl Lambrecht Corporation. 4204 N.
