Optimization of Resonators

Using the tools developed in Section X, we will now address considerations for choosing the optimum dimensions and parameters of a coupled Fabry-Perot interferometer (CFPI) shown in Fig. 13. 

A given mesh reflectivity imposes a lower bound for the beam-waist radius, below which appreciable coupling losses can occur. The basic problem is that a Gaussian beam will continue to diverge upon repeated reflection within a planar interferometer as shown in Fig. 12b. If the spherical mirror of the cavity is designed to match the original (input) beam waist, beam divergence will cause a mismatch at the output, which 

Arnaud et al. gave an expression that leads to the following criterion for restricting the coupling loss to 1 dB or less  

Optimization of Rj must take into account the sample cavity finesse,
