The spectral noise power of photon number fluctuations inside a driven high-finesse Fabry-Perot optical resonator is measured through the resonator-enhanced momentum diffusion of ultracold atoms trapped within. Light-induced heating of the trapped atoms is quantified by their rate of Evaporation from a finite-depth intra cavity optical trap. The relevance of cavity-enhanced momentum diffusion to cavity-enhanced measurements of atomic ensembles is discussed.
