Abstract

We present measurements of the coefficient of thermal expansion (alpha) of an all-sapphire, cryogenic, Fabry-Perot optical cavity between 5 K and 77 K. The cavity is to be used as a secondary optical frequency reference. Measurements were made by tracking the frequency of the cavity relative to a free-running Nd:YAG non-planar ring laser. We find that alpha = (1.56 +/- 0.84) x 10(-12)T((3.0 +/- 0.2)) [K-1].
