A method is described for measuring the wavelength of a laser beam using a pseudo heterodyne converter in order to compare the wavelength with that of a beam from a Zeeman laser. With this method, an oscillating laser at a single frequency is converted to a pseudo heterodyne source by retardation that is modulated by a serrodyne waveform. This method is used in an interferometer made for comparing optical phase. The results from measuring the wavelength of light emitted by a laser diode suggest that this method is better for measuring laser beam wavelengths than conventional methods.
