Abstract

We present measurements of the frequency-temperature dependence of a cryogenic all-sapphire Fabry-Perot optical cavity to be used as an optical frequency reference. Measurements were made by tracking the frequency of the cavity relative to a free-running Nd:YAG non-planar ring laser. Measurements cover the temperature range of 5 K to 77 K.
