| Zusammenfassung | A scheme is presented that allows quantum-noise-limited, background-free signal detection on high-resolution spectroscopy, atom-light interferometers, and otical clocks. The method combines the electron-shelving technique with a removal of all absorbers not participating in the excitation scheme. Application to the ¹S0-3P1 transition of Ca demonstrated a more than fourfold improvement of the signal-to-noise ratio with respect to the precious photon shot-noise limit. |
