| Zusammenfassung | The vacuum wavelength of a 544 nm iodine-stabilised He-Ne laser was measured by means of the PTB's Michelson interferometer, which had been designed for highly accurate wavelength comparisons. One of the two longitudinal models of the internal mirror He-Ne laser was selected and frequency stabilised using FM saturation spectroscopy at iodine by means of an external cell. Reference wavelengths were obtained from an I2-stabilised He-Ne laser at 633 nm and an 12-stabilised Ar+-laser at 515 nm. The wavelength of the 544nm 12-stabilised He-Ne laser was found to be λ = 543,51633304 nm with a relative standard uncertainty of 8,4. 10-11 |
