Current Optical Frequency Atomic Clocks are limited by the linewidth of the laser probing the ‘clock’ transition. To enable the laser to be narrowed a very low expansion Fabry-Perot cavity is used to lock the laser to. The current limitation of this cavity is the thermal noise from the mirrors, in the form of Brownian thermal noise and thermoelastic noise. These noise sources can be calculated analytically and numerically, the choice of materials other ways to lower this noise will be discussed.
