“…One point in the spectrum can be fixed in relation to the FSR correction so as to be able to ''lock'' one peak to a reference position while still allowing for linear transformations. We could reproduce literature values [48,49] within AE5 Â 10 À4 cm À1 . The measurement accuracy is better for shorter scans.…”

“…Line positions were calibrated to better than 0.001 cm −1 using a 10 cm long 12 C 2 H 2 reference cell. 13 The gas mixture was prepared by on-line mixing Ar (Air liquide) with a premixed sample (10% NH 3 /90% Ar; Air liquide) resulting in a 1% NH 3 /Ar mixture which was injected at a flow rate of 4460 sccm (where sccm denotes cubic centimeter per minute at standard conditions for temperature and pressure). The reservoir (p 0 ) and residual (p ∞ ) pressures were kept constant at 53 kPa and 2 Pa, respectively.…”

“…For example, in quantum optics, the QED interaction between a colored vacuum and a quantum system can be probed by examining the intensity of light transmitted through a high-Q cavity [1]. In atomic physics, the transmission of light through a resonant vapor can be used to measure atomic collision cross sections [2], while in analytical chemistry, transmitted light can reveal the presence of trace compounds [3]. New means for precisely measuring both the relative and absolute strength of an electromagnetic field, especially ones with advantageous and unique characteristics, are therefore of considerable relevance for a great many researchers.…”

SUPPLEMENTARY NOTES ABSTRACTAcross a broad range of disciplines, the accurate determination of an electromagnetic wave's amplitude (either absolute or relative) has considerable relevance. Here, we demonstrate a novel and potentially very precise method for making intensity measurements based on the atomic stabilization of electromagnetic field-strength. For ease of reference, and by analogy to atomic clocks, we refer to this field-strength stabilization system as an atomic candle. While the candle's original purpose was to create a field with long-term intensity stability, its very nature makes it ideal for detecting subtle amplitude changes in strong electromagnetic fields, a problem that is fundamentally different from detecting weak signals in the presence of noise. In this paper, we discuss proof-of-principle experiments demonstrating the atomic candle's ability to make precise measurements of absorption coefficients and indices of refraction.
