Abstract

We report the first spectroscopy of optical lattice-confined Yb atoms. We demonstrate 20 Hz linewidths using the highly forbidden clock transition (1S0-3P0) in metrologically superior even-isotope174Yb atoms in a one-dimensional optical lattice.

We report high resolution spectroscopy of optical lattice-confined 174Yb atoms. We demonstrate spectroscopic linewidths as narrow as 4 Hz (full-width at half-maximum) using the highly forbidden clock transition (1S0-3P0) in a one-dimensional optical lattice.

A transportable optical lattice clock using 171Yb

Gregor Mura, Tobias Franzen, C. Abou-Jaoudeh +5 more

We present first results on the spectroscopy of the1S0→3P0transition at 578nm in a transportable171Yb optical lattice clock. With the Yb atoms confined in a one-dimensional optical lattice, we have observed linewidths below 200 Hz, limited by saturation broadening. Currently the system is being upgraded towards full clock operation and use of more compact and robust subsystems.

We have developed a one-dimensional optical lattice clock with ultracold 171Yb atoms. The absolute frequency of the 1S0(F = 1/2) - 3P0(F = 1/2) clock transition in 171Yb is determined to be 518 295 836 590 864(28) Hz with respect to the SI second. Details of the experimental setups and atom trapping results are also described.

Hertz-Level Clock Spectroscopy of 171 Yb Atoms in a One-Dimensional Optical Lattice

Meng-Jiao Zhang, Hui Liu, Xi Zhang +4 more

An ultra-narrow spectroscopy of clock transition with high signal-to-noise ratio is crucial for a high-performance atomic optical clock. We present a detailed study about how to obtain a Hertz-level clock transition spectrum of 171 Yb atoms. About 4 × 10 4 atoms are loaded into a one-dimensional optical lattice with a magic wavelength of 759 nm, and a long lifetime of 3 s is realized with the lattice power of 1 W. Through normalized shelving detection and spin polarization, 171 Yb clock spectroscopy with a Fourier-limited linewidth of 5.9 Hz is obtained. Our work represents a key step toward an ytterbium optical clock with high frequency stability.

Direct Excitation of the Forbidden Clock Transition in Neutral Yb174 Atoms Confined to an Optical Lattice

Zeb W. Barber, Chad Hoyt, Chris W. Oates +3 more

We report direct single-laser excitation of the strictly forbidden (6s2)1S0 <--> (6s6p)3P0 clock transition in 174Yb atoms confined to a 1D optical lattice. A small (approximately 1.2 mT) static magnetic field was used to induce a nonzero electric dipole transition probability between the clock states at 578.42 nm. Narrow resonance linewidths of 20 Hz (FWHM) with high contrast were observed, demonstrating a resonance quality factor of 2.6 x 10(13). The previously unknown ac Stark shift-canceling (magic) wavelength was determined to be 759.35 +/- 0.02 nm. This method for using the metrologically superior even isotope can be easily implemented in current Yb and Sr lattice clocks and can create new clock possibilities in other alkaline-earth-like atoms such as Mg and Ca.

Lattice-based optical clock using an even isotope of Yb

Zeb W. Barber, Chad Hoyt, J. E. Stalnaker +5 more

We describe progress toward an optical lattice clock based on an even isotope of Yb. The 1S0 → 3P0 clock resonance in 174Yb is accessed through a magnetically induced spectroscopic technique. Using ≈1mT static magnetic fields and ≈10 μW of probe light power we generate Rabi frequencies of several hertz. The narrow spectroscopic features that result (< 10 Hz FWHM) require a highly stabilized laser at the clock transition wavelength of 578 nm. We describe a new all solid-state laser system that shows hertz level stability. In order to cancel the slow drift of the cavity, spectroscopy is performed on the clock transition to provide feedback to the laser. Using a Ca neutral atom frequency standard as a reference oscillator,we show high stability and an effective method for investigating clock frequency shift systematics.
