Abstract

/sup 172/Yb/sup +/ ions in an RF trap have been laser-cooled to 2 K by driving the /sup 2/S/sub 1/2/-/sup 2/P/sub 1/2/ transition at 369.5 nm. Observations of metastable F-state populations at low pressure are reported for large numbers of Yb/sup +/ ions in the trap. A narrow-linewidth ring dye laser for probing an S-D or S-F transition in trapped Yb/sup +/ is considered.>

High-resolution spectroscopy of the 435 nm /sup 2/S/sub 1/2/-/sup 2/D/sub 3/2/ transition in trapped /sup 171/Yb/sup +/

Chr. Tamm, V. Bühner

Single /sup 171/Yb ions are laser cooled in a miniature radiofrequency trap. We demonstrate high-resolution spectroscopy of the potential frequency-standard reference transition from the F=0 ground-state sublevel to the metastable /sup 2/D/sub 3/2/ (F=2, m/sub F/=0) level at a wavelength of 435 nm. Presently achieved minimum linewidths are in the range of 80 Hz.

Investigation for high-resolution spectroscopy of the /sup 2/S/sub 1/2 /-/sup 2/D/sub 5/12/ transition of laser-cooled trapped Yb/sup +/

K. Sugiyama, Jun Yoda

We drove the /sup 2/S/sub 1/2 /-/sup 2/D/sub 5/12/ transition of laser-cooled trapped Yb/sup +/ by frequency-doubled diode-laser radiation. The /sup 2/F/sub 7/2/ state, pumped by driving this transition, was deexcited by irradiation at 3.43 /spl mu/m, 638 nm, and 828 nm.

Summary form only given, as follows.Single /sup 171/Yb ions are laser cooled in a Paul trap, using laser sources based on semiconductor diode lasers. Excitation of the potential frequency-standard reference transition to the /sup 2/D/sub 3/2/, (F=2) hyperfine sublevel of /sup 171/Yb/sup +/ at a wavelength of 435.5 nm is demonstrated.

Diode-laser-based light sources for laser cooling of trapped Yb/sup +/ ions

K. Sugiyama, A. Wakita, A. Nakata

We are developing a light source at 370 nm for driving the /sup 2/S/sub 1/2/-/sup 2/P/sub 1/2/ cooling transition by sum-frequency mixing of radiation from two diode lasers with a doubly resonant external cavity. To drive the /sup 2/D/sub 3/2/-/sup 3/D[3/2]/sub 1/2/ repumping transition at 935 nm, we developed two types of external cavity diode lasers. Applications of them to laser-cooled trapped Yb/sup +/ ions are also presented.

Development of a trapped Yb/sup +/ frequency standard: efficient quenching of population trapping

David J. Seidel, Lute Maleki

We report on a study to determine the efficiency of various buffer gases in quenching the population trapping states of laser excited ytterbium ions. The ions were confined in an rf/dc hybrid trap, and their /sup 2/S/sub 1/2//spl hArr//sup 2/P/sub 3/2/ transition was excited with 329 nm laser light. Buffer gases used include H/sub 2/, N/sub 2/, CO/sub 2/, Ar, and He at several different pressure regimes. We have identified N/sub 2/ to be highly efficient in quenching the population of the trapping states, and thus be the most suitable buffer gas to use with ytterbium for the development of a trapped ion microwave frequency standard.

Clearly resolved secular sidebands on the /sup 2/S/sub 1/2/-/sup 2/D/sub 5/2/ 674 nm clock transition in a single trapped Sr/sup +/ ion, and prospects for trapped ion frequency standards

A pre-stabilised 674 nm diode laser has been narrowed by locking it to a high-finesse ULE cavity and kHz error signals have been observed. Confinement of single laser cooled Sr/sup +/ ions in a miniature RF trap has been demonstrated and micromotion reduction achieved. RF trap secular sidebands have been observed on the Sr/sup +2/S/sub 1/2/-/sup 2/D/sub 5/2/ 674 nm clock transition. The implication of these results, and similar results in other trapped ion systems will be discussed.
