Fabry-Perot temperature dependence and surface-mounted optical cavities

摘要: Factors that contribute to the temperature dependence of a resonant frequency in low-expansion optical cavity are discussed, including deformation at ends due different coefficients thermal expansion (CTE) spacer, optically-contacted mirror substrate and coating. A model is presented incorporates finite-element-analysis ends. measurement versus mode used along with deduce spacers CTE profile. The measured profile correlates very well separate experiment utilizing temporary surface-mounted Fabry-Perot fabricated on outside spacer hydroxy-catalysis bonding.
