Analysis of the frequency shift in coherent population trapping resonance's dynamic continuous-wave spectroscopy at the phase-jump modulation and its comparison with the conventional approach
E. D. Chivilis, E. A. Tsygankov
We present the research of dynamic continuous-wave spectroscopy of the coherent population trapping resonance at the phase-jump modulation. Î system of levels supplemented by a no…
Dual-frequency Doppler-free crossover resonance with suppressed magnetic-field sensitivity for compact optical frequency standards
D. S. Chuchelov, M. I. Vaskovskaya, E. A. Tsygankov +3
We report the observation and characterization of a high-contrast dual-frequency Doppler-free ground-state crossover resonance in the D1 line of 87Rb.The crossover appears at a two…
Nuclear-spin-related properties of~the dual-frequency Doppler-free resonance
E. A. Tsygankov, K. M. Sabakar, D. S. Chuchelov +4
We investigate the dual-frequency Doppler-free resonance in the D1 line of alkali-metal atoms for any accessible value of the nuclear spin I. The consideration is performed using t…
Single-frequency inverted Doppler-free resonance as a platform for chip-scale optical clock
E. A. Tsygankov, D. S. Chuchelov, M. I. Vaskovskaya +3
We report on the possibility to obtain a high-quality inverted Doppler-free resonance in D1 line of alkali-metal atoms in the single-frequency regime. The counter-propagating optic…
Frequency locking: a distinctive feature of the coherent population trapping and the stationarity effect
E. A. Tsygankov, D. S. Chuchelov, M. I. Vaskovskaya +3
We study the case where phase modulation of the harmonic signal is used to obtain the error signal for the frequency stabilization to a reference atomic transition. High-frequency…
