Optical pumping has been demonstrated to improve the frequency stability of cesium beam clocks without compromising lifetime. This technology has been successfully implemented in metrology clocks for national laboratories but to-date no commercial products have been marketed.
Oscilloquartz is developing an optically pumped cesium beam clock to meet the needs of metrology, defense, space and telecom applications. The company’s first complete optical cesium clocks are under test and preliminary performance results have shown that it achieves a tenfold stability improvement over current magnetic deflection atomic clocks.
