These examples offer a view into what the chip-scale era in timekeeping will look like. The SA.45s CSAC delivers the accuracy and stability of an atomic clock to portable applications for the first time — Read more »
As innovative as the CSAC’s design is, most users will gauge its value by its performance benchmarks. In summary, these include the following:Read more »
The SA.45s CSAC employs coherent population trapping (CPT) to interrogate an atomic frequency. A laser illuminates atoms in a resonance cell with polarized radiation at two sidebands separated by the atomic resonance frequency. The atoms are excited Read more »
