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…
