Sr lattice clock with inaccuracy below 10
Martin M. Boyd, Andrew D. Ludlow, Sebastian Blatt +4
Aided by ultra-high resolution spectroscopy, the overall systematic uncertainty of the - clock resonance for lattice-confined Sr has been characterized…
Dynamic cancellation of ac Stark shift for pulsed EIT/Raman optical lattice clocks
T. Zanon-Willette, A. D. Ludlow, S. Blatt +3
We propose a combination of Electromagnetically Induced Transparency (EIT)/Raman and pulsed spectroscopy techniques to accurately cancel frequency shifts arising from EIT fields in…
Optical atomic coherence at the one-second time scale
Martin M. Boyd, Tanya Zelevinsky, Andrew D. Ludlow +4
Highest resolution laser spectroscopy has generally been limited to single trapped ion systems due to rapid decoherence which plagues neutral atom ensembles. Here, precision spectr…
OH hyperfine ground state: from precision measurement to molecular qubits
Benjamin L. Lev, Edmund R. Meyer, Eric R. Hudson +3
We perform precision microwave spectroscopy--aided by Stark deceleration--to reveal the low magnetic field behavior of OH in its ^2Π_{3/2} ro-vibronic ground state, identifying two…
Narrow Line Photoassociation in an Optical Lattice
T. Zelevinsky, M. M. Boyd, A. D. Ludlow +5
With ultracold Sr in a 1D magic wavelength optical lattice, we performed narrow line photoassociation spectroscopy near the SP intercombination transition.…
High resolution atomic coherent control via spectral phase manipulation of an optical frequency comb
Matthew C. Stowe, Flavio C. Cruz, Jun Ye
We demonstrate high resolution coherent control of cold atomic Rubidium utilizing spectral phase manipulation of a femtosecond optical frequency comb. Transient coherent accumulati…
