High-bandwidth transfer of phase stability through a fiber frequency comb.

Optics express

Scharnhorst N, Wübbena JB, Hannig S, Jakobsen K, Kramer J, Leroux ID, Schmidt PO.
PMID: 26367634
Opt Express. 2015 Jul 27;23(15):19771-6. doi: 10.1364/OE.23.019771.

We demonstrate phase locking of a 729 nm diode laser to a 1542 nm master laser via an erbium-doped-fiber frequency comb, using a transfer-oscillator feedforward scheme which suppresses the effect of comb noise in an unprecedented 1.8 MHz bandwidth....

Long-distance remote comparison of ultrastable optical frequencies with 10(-15) instability in fractions of a second.

Opt Express. 2010 Sep 27;18(20):21477-83. doi: 10.1364/OE.18.021477.

We demonstrate a fully optical, long-distance remote comparison of independent ultrastable optical frequencies reaching a short term stability that is superior to any reported remote comparison of optical frequencies. We use two ultrastable lasers, which are separated by a...

Precision spectroscopy by photon-recoil signal amplification.

Nature communications

Wan Y, Gebert F, Wübbena JB, Scharnhorst N, Amairi S, Leroux ID, Hemmerling B, Lörch N, Hammerer K, Schmidt PO.
PMID: 24477261
Nat Commun. 2014;5:3096. doi: 10.1038/ncomms4096.

Precision spectroscopy of atomic and molecular ions offers a window to new physics, but is typically limited to species with a cycling transition for laser cooling and detection. Quantum logic spectroscopy has overcome this limitation for species with long-lived...
