摘要：

The present work for the first time reports on studies of properties of dynamically excited coherent population trapping (CPT) resonances in cells without buffer gas (both with and without anti-relaxation coating of their inner walls). Over the 0-3 kHz range of CPT resonance scanning frequencies, the discriminant curve slope was determined, as well as measured stability of atomic clocks. The work provides details of the experiments and analyses prospects of application of results for improvement of atomic clock stability. The work also discusses the newly discovered different character of CPT resonance shape evolution in cells with and without buffer gas.
