“…The transmitted laser intensity thus acted as a measure of atomic population in the F = 2 level, so any microwave-induced oscillation of this population was observed as oscillations in the transmitted light and appeared as a bright line on the spectrum analyzer. Because our atomic-candle signal is associated with population oscillations occurring at 2tJm [13], we were able to measure 6pop very easily by simply recording the amplitude of the bright line on the spectrum analyzer at 2uJm-We note that Doppler broadening played no role in our experiments as a consequence of Dicke narrowing [26], [27].…”

“…Briefly, the modulated field induces atomic population oscillations, and the amplitude of these oscillations, Spop, exhibits resonance when the field's modulation frequency, Wm, matches the atom's Rabi frequency, Q [18].-' There are at least two diff'erent types of Rabiresonance [13], and one of these finds appHcation in a device called an atomic candle, in which field amplitude is locked to the peak of the Rabi-resonance in much the same way as field frequency is stabilized in an atomic clock [19], [20]. As discussed elsewhere [13], the atomic-candle signal has the form:…”

SUPPLEMENTARY NOTES ABSTRACTSlow variations in cavity-Q and microwave power are thought to play a role in the long-term frequency stability of gas-cell atomic clocks. Here, we use an atomic-candle method to study the aging of a Tfion microwave cavity's resonant frequency and quality factor when a glass resonance cell containing Rb^'' loads the cavity. Our results suggest that the alkali vapor coats the inside glass surface of the resonance cell with a thin metallic film; and that, as this film evolves, the quality factor degrades. (In our experiments, the quality factor changed by 30% over a timescale of months.) More generally, the present work demonstrates the efficacy of the atomic-candle method for investigating cavity resonances. In particular, we show that, when used in conjunction with more traditional methods, the atomic-candle method has the potential to reveal information on a cavity mode's spatial profile.

Slow variations in cavity Q and microwave power are thought to play a role in the long-term frequency stability of gas-cell atomic clocks. Here, we use an atomic-candle method to study the aging of a TE 011 microwave cavity's resonant frequency and quality factor when a glass resonance cell containing Rb 87 loads the cavity. Our results suggest that the alkali vapor coats the inside glass surface of the resonance cell with a thin metallic film, and that as this film evolves the quality factor degrades. More generally, the present work demonstrates the efficacy of the atomic-candle method for investigating cavity resonances. In particular, we show that when used in conjunction with more traditional methods, the atomic-candle method has the potential to reveal information on a cavity mode's spatial profile.

We present a feasibility study of a real-time visualization method for electromagnetic fields. When a resonant laser is used to irradiate gaseous atoms enclosed in a glass cell, the atoms absorb the light and immediately radiate as fluorescence. If a resonant laser and electromagnetic field are used to irradiate the gaseous atoms simultaneously, fluorescence of the light is stronger. The difference between the strength values of fluorescence of light can be used for electromagnetic field visualization. We succeeded in demonstrating a real-time visualization of electromagnetic fields radiated from a horn antenna and an aperture of a waveguide in free space.
