quantum-noise-limited absorption sensitivity; frequency comb spectroscopy

Sažetak
We achieve a quantum-noise-limited absorption sensitivity of 1.7*10^-12 cm-1 per spectral element at 400 s of acquisition time with cavity- enhanced frequency comb spectroscopy, the highest demonstrated for a comb-based technique. The system comprises a frequency comb locked to a high-finesse cavity and a fast-scanning Fourier transform spectrometer with an ultralow-noise autobalancing detector. Spectra with a signal-to- noise ratio above 1000 and a resolution of 380 MHz are acquired within a few seconds. The measured absorption line shapes are in excellent agreement with theoretical predictions.
