Fabry-Perot temperature dependence and surface-mounted optical cavities
Published
Author(s)
Abstract
Factors that contribute to the resonance temperature dependence of low-expansion optical cavities are discussed, including deformation at the cavity ends due to different coefficients of thermal expansion (CTE) of the spacer, optically-contacted mirror substrate and coating. A model of temperature dependence is presented that incorporates finite-element-analysis of the cavity ends. Measurements of frequency versus temperature of a cavity mode are used along with the model to measure a spacer s CTE profile. The measured profile correlates very well with a separate experiment utilizing a temporary surface-mounted Fabry-Perot cavity fabricated on the outside of the spacer with hydroxy-catalysis bonding. Such temporary cavities may be useful for accurately measuring the CTE of potential spacer -glass pieces, enabling cavity designs with near zero temperature dependence at specified temperatures.Proceedings Title
