摘要: The authors have observed very narrow two-photon millimetre resonances in sodium, corresponding to nS (n+1)S transitions (principal quantum number n ranging from 32 40). linewidth, of the order 10 kHz for frequencies around 100 GHz, is transit-time limited. variation with defects series studied. precision experiments can still be improved and applications metrology a direct frequency determination Rydberg constant are possible.
