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. The polarization 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.
