Optical pumping cesium beam tubes

WebLaser-pumped cesium beam atomic clocks have been under development over the last 20 years. Optical pumping allows for the utilization of essentially 100% of the atoms in the beam, " improv- ing the clock signal-to-noise ratio over that of similar beam clocks using magnetic state selection by factors between 5 and 10. WebSep 30, 2024 · Optical pumping is a conceivable mechanism for breaking the symmetry between equivalent spin configurations in TMDs. Recent studies have shown that pumping individual monolayers or heterostructures of TMDs with circularly polarized light can generate spin imbalances with microsecond-long relaxation times ( 19 , 20 ).
