“…5. These results and previous measurements 7,17,19 are summarized in Table II. The agreement with previous high-accuracy work of similar uncertainty is excellent, supporting the assertion that these measurements of Doppler-free saturated-absorption transitions in tellurium are accurate standards at the ±1 MHz level.…”

We have constructed a broadband apparatus for wavelength metrology capable of absolute accuracy at a level of better than 2 parts in 10 9. An evacuated plane-parallel Fabry-Pérot interferometer with continuously adjustable mirror separation is used to compare the wavelength of a single-frequency tunable laser with that of an iodine-stabilized HeNe laser used as a wavelength standard. This work details apparatus construction, a thorough investigation of systematic errors, and data analysis. The wavelengths of five Doppler-free 130 Te 2 transitions in the region from 475.6 to 490.8 nm have been measured and are found to be in excellent agreement with previous measurements. In addition, the wavelengths of five previously unmeasured 130 Te 2 transitions spanning the region from 424.9 to 462.3 nm have been determined for use as new reference wavelength standards.

“…Doppler-free absorptions in molecular tellurium ͑ 130 Te 2 ͒ are used as local frequency references at 467 nm. Modulation transfer features are generated using the technique described by Ma et al [18], using a cell characterized by Barwood et al [19]. Tellurium features in the vicinity of the search region were measured by comparison with an iodine-stabilized He-Ne laser [20].…”

The 2 S 1͞2-2 F 7͞2 electric octupole ͑E3͒ transition in 172 Yb 1 has been detected by observing quantum jumps in a single laser cooled ion, stored in an electrodynamic trap. The transition frequency is 642 116 785.3(0.7) MHz ͑1s͒. Consideration of the transition rate and laser parameters implies a 2 F 7͞2 level lifetime of 3700 days. This is the first time an atomic E3 transition has been driven. This transition has applications as an optical frequency reference. [S0031-9007(96)02175-8]

“…The 606 nm dye laser was frequency locked to a 1 m evacuated Fabry-Perot etalon [12,13] To unambiguously assign the 606 nm etalon order number, the dye laser frequency was measured using a fringe fractioning wavemeter [14] with an accuracy of 30 MHz .…”
