摘要: The circular polarized laser beam of the 'magic' wavelength may be used for mixing {sup 3}P{sub 1} state into long-living metastable 0}, thus enabling strictly forbidden 1}S{sub 0}-{sup 0} 'clock' transition in even isotopes alkaline-earth-metal-like atoms, without a change frequency. In odd adjust to an optimum value linewidth clock transition, originally enabled by hyperfine mixing. We present detailed analysis various factors influencing resolution and uncertainty optical frequency standard based on atoms exposed simultaneously lattice standing wave additional 'state-mixing' wave, including estimations wavelengths, Rabi frequencies state-mixing transitions, ac Stark shifts ground states divalent atoms.
