摘要
We have observed the hyperfine spectrum of Te-130(2) 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 10(9) in the best case to 1.4 parts in 10(8) 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. (C) 1997 Optical Society of America.
