摘要：

The frequencies of six iodine-stabilized He-Ne-lasers developed at the UPT have been compared with one of the PTB lasers. The lasers were operated at λ = 633 nm. Their frequencies were stabilized to the line centres of hyperfine structure (hfs) components of the R(127) 11-5 absorption line of 127I2 using the third-harmonic detection technique. The stabilized frequencies of the UPT lasers averaged for each laser over the four hfs components d, e, f, and g are distributed in two groups. The frequencies of one group of three lasers are close to the frequency of the PTB laser with maximum deviations of +4 kHz to -9 kHz. The frequencies of the other three lasers are offset by -38 kHz with deviations of +8 kHz to -4 kHz. The maximum frequency deviations between all six lasers are approximately one order of magnitude smaller than the uncertainties of the recommended wavelength values [1] for this laser system, demonstrating its high potential for the realization of the metre and for high-precision spectroscopy.
