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…
A nonlinear frequency shift caused by asymmetry of the coherent population trapping resonance: a generalization
E. A. Tsygankov, D. S. Chuchelov, M. I. Vaskovskaya +3
We investigate the coherent population trapping resonance induced by a polychromatic optical field with an asymmetric spectrum, i.e., whose sidebands equidistant from the carrier h…
Effect of depolarizing and quenching collisions on contrast of the coherent population trapping resonance
K. M. Sabakar, M. I. Vaskovskaya, D. S. Chuchelov +4
We investigate the effect of buffer gases on the coherent population trapping resonance induced by a -polarized optical field in Rb atoms. Our experimental results show t…
Intensity nonlinearity of the error-signal frequency shift in the modulation spectroscopy of dark resonances and approaches to its reduction
E. A. Tsygankov, S. V. Petropavlovsky, M. I. Vaskovskaya +5
We have found that the error-signal frequency corresponding to the coherent population trapping resonance can be displaced from that of "" transition unperturbed by the optica…
Dynamic continuous-wave spectroscopy of coherent population trapping at phase-jump modulation
M. Yu. Basalaev, V. I. Yudin, A. V. Taichenachev +5
A method of dynamic continuous-wave spectroscopy of coherent population trapping (CPT) resonances using phase modulation of the jump type is developed. The time evolution of the sp…
