Abstract: | Ultra-stable optical cavities are widely used for laser frequency
stabilization. In these experiments the laser performance relies on
the length stability of the Fabry--Perot cavities. Vibration-induced
deformation is one of the dominant factors that affect the stability
of ultra-stable optical cavities. We have quantitatively
analysed the elastic deformation of Fabry--Perot cavities with various shapes
and mounting configurations. Our numerical result facilitates a
novel approach for the design of ultra-stable cavities that are
insensitive to vibrational perturbations. This approach can be
applied to many experiments such as laser frequency stabilization,
high-precision laser spectroscopy, and optical frequency standards. |
