Abstract

We have observed the hyperfine spectrum of  130Te2 that coincides with the visible emissions of an Ar+ laser by using Doppler-free polarization spectroscopy. The vacuum wavelengths of the 16 transitions observed have been measured by a high-precision wavemeter with an uncertainty ranging from 6 parts in 109 in the best case to 1.4 parts in 108 in the worst case. These measurements provide a set of precise molecular references to frequency locking of visible lines of Ar+ lasers used in high-precision laser spectrometers.
