Abstract: Resonances of coherent population trapping (CPT) are recorded during multifrequency pumping of a cell with Rb-87 by radiation from an external-cavity diode laser under the combined action of microwave and VHF modulation of the injection current. The relative amplitudes of the resonances and the frequency intervals are measured.
Keywords: CPT resonance, diode laser, optical pumping, frequency standard.
