-shift in a short-baseline atomic interferometer-gravimeter
D. N. Kapusta, A. E. Bonert, A. N. Goncharov +6
This paper presents the first experimental observation and investigation of a lineshape-asymmetry-caused shift (LACS) in a short-baseline atomic interferometer-gravimeter. It is sh…
Lineshape-asymmetry-caused shift in atomic interferometers
V. I. Yudin, O. N. Prudnikov, A. V. Taichenachev +7
We investigate the shift caused by asymmetry of spectroscopic lineshape in atomic interferometers, which has not previously been discussed in the scientific literature. This asymme…
An effective model for describing coherent population trapping resonances, which correctly takes into account the off-resonant frequency components in periodically modulated laser field
V. I. Yudin, M. Yu. Basalaev, A. V. Taichenachev +1
We have developed an effective mathematical model to calculate the coherent population trapping (CPT) resonance in periodically modulated light, when the modulation frequency v…
Optical clock based on two-photon spectroscopy of the nuclear transition in ion Th in a monochromatic field
V. I. Yudin, A. V. Taichenachev, O. N. Prudnikov +4
For the isotope Th we investigate the possibility of two-photon laser spectroscopy of the nuclear clock transition (148.38 nm) using intense monochromatic laser field at tw…
Theory of composite Ramsey sequences of radiofrequency pulses beyond the rotating wave approximation
V. I. Yudin, O. N. Prudnikov, A. V. Taichenachev +3
We develop a theory of composite Ramsey sequences of rf pulses interacting with the Zeeman structure at the long-lived atomic level, beyond the rotating wave approximation. Such se…
