| Popis: | The wavelengths of an Ar+ laser and of a He-Ne laser at 515 nm and 612 nm, respectively, have been compared with the wavelength of a He-Ne laser at 633 nm. All the lasers involved were stabilized by using saturated absorption in iodine-127. The wavelength ratios were related to the He-Ne laser at 633 nm stabilized to the hyperfine component i of the rotational and vibrational transition R(127) 11-5 of iodine. For the Ar+ laser locked to the component a3 of the P(13) 43-0 line, the ratio determined was λa3/λi = 0.813 081 2954 × (1 ± 5 10-10) and for the 612 nm He-Ne laser locked to the component o of the R(47) 9-2 line, the measured ratio was λo/λi = 0.966 791 6050 × (1 ± 3 10-10). |
