摘要：
Singly ionized ytterbium offers a number of possibilities to realize frequency standards in the optical frequency range, Two narrow-linewidth reference transitions, one at a wavelength 436 nm and the other at 467 nm. are of particular interest for practical implementations of single-ion optical clocks. The frequency ratio of these transitions is expected to be a very sensitive probe for the constancy of the fine structure constant. We outline our related experimental work and in particular the status of the 436 nm (688 THz) single-ion optical frequency standard developed at PTB.
