2 Modes of Fabry–Pérot Cavities and Readout Beams

It is well known that a Fabry–Pérot cavity has eigenmodes corresponding to eigenfrequencies determined by its length and geometries defined by the shape of the mirrors. It is also well known that cavities with spherical mirrors are resonant for Hermite–Gauss or Laguerre–Gauss modes. Recently more exotic shapes have been proposed in order to reduce the thermal noise.
