چکیده انگلیسی
We have built an accurate wavelength meter based on a Michelson interferometer characterized by a high stability velocity moving system. The unknown wavelength is determined from the Doppler frequency shifts of the output beams of the Michelson interferometer. The reference laser is a frequency stabilized helium-neon laser. A counting resolution of 2.6Â ÃÂ 10â9 for an integration time of 30Â s has been obtained. The apparatus has been used to determine the wavelength of a second frequency stabilized helium-neon laser and the result has been compared to those given by two different methods: frequency beating in regards to the national reference and using a commercially available scanning-Michelson wavemeter. Taking into account the statistical errors, we achieved a relative accuracy on the unknown wavelength of 6.4Â ÃÂ 10â8 at 1Ï.
