Abstract A new type of laser wavemeter based on polarimetric interferometer is proposed. This wavemeter can achieve the accuracy of 10-6 on micrometric range. This wavemeter is less sensitive to environmental temperature, wavelength shift, and index of air with reduced displacement range. The experimental results of measured value and uncertainty for two unknown laser sources (DL100-Toptica and Nd:YAG) are presented. The experimental comparisons between our own-developed wavemeter and a commercial wavemeter are also described.
