We have established a compact and transportable I/sub 2/-stabilized Nd:YAG laser for international comparisons of laser frequency. The root Allan variance of the portable laser has reached 3.9/spl times/10/sup -14/ when the integration time is longer

The characteristics of Yb/sup +/ held in a RF trap in the presence of a light buffer gas by irradiation with resonant light beams, including those for depleting the metastable state of the /sup 2/D/sub 3/2/ and /sup 2/F/sub 7/2/ states, are studied.

Positive and negative carbon cluster ions produced by laser ablation have been simultaneously stored in an RF ion trap. The size distributions of the stored cluster ions, which were measured by means of ion dumping followed by time-of-flight mass ana

Multiply charged ions of Xe gases were produced through inner‐shell photoionization by using synchrotron radiation, and were stored in an rf ion trap. The experimental apparatus for trapping and probing multiply charged ions is described, and resul

We have observed saturated absorption of the v/sub 1/+v/sub 3/ band of /sup 13/C/sub 2/H/sub 2/ using an intracavity cell. These narrow lines can be expected to use as a frequency standard at 1550 nm region. We also demonstrate it is possible to satu

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

For spectroscopy of the /sup 2/S/sub 1/2 /-/sup 2/D/sub 5/2/ transition of Yb/sup +/, we are developing a laser-diode spectrometer composed of a master laser locked to a high-finesse cavity, a phase-locked offset laser for frequency scanning, and a f
