摘要：

A combined infrared-optical frequency-standard scheme has been demonstrated with a single ion of ytterbium. The optical S-2(1/2)-D-2(5/2) reference transition at 411 nm and the infrared (2)F(7/2)D(5/2)3.43-mu m transition were driven sequentially. The structure of the infrared F-2(7/2)-D-2(5/2) reference transition at 3.43 mu m has also been studied. Infrared transition linewidths of 300 kHz were observed. The output of a Nd:YAG laser and an extended-cavity diode laser were difference-frequency mixed in a crystal of AgGaS2 to produce narrow-linewidth light at 3.43 mu m. Both lasers were frequency stabilized to high-finesse reference cavities. (C) 1998 Optical Society of America.
