Abstract

A precise, repeatable and stable optical frequency source is required for many modern spectroscopy experiments. Frequency combs have proven invaluable to many, but are not obtainable for others due to their high cost. Using a GPS disciplined oscillator, a stabilized Fabry-Pérot cavity, a relatively low-cost wavemeter and standard RF equipment, we have achieved a reliable laser system with a $10^{-9}$ or better frequency uncertainty at a fraction of the cost. With this system we have measured approximately 3000 transitions in $^{130}$Te$_2$ continuously between $664$ and $676~$THz to $\sim~0.0001$~cm$^{-1}$ precision. The system is described in detail, and the possibility of improving our knowledge of the excited states of $^{130}$Te$_2$ is considered.
