Abstract

The laser interferometers are intended for high-precision measurement of distances and displacements. The calibration equipment for the definition of real meaning of the laser radiation wavelength and investigation of wavelength stability and reproducibility of the laser radiation in the laser interferometers is presented in paper. The laser radiation frequency was measured with the heterodyne method using the developed laser frequency iodine standard 633 nm. The system was used for calibration the frequency of the He-Ne Zeeman laser used in the two frequency laser interferometer.
