Paper Abstract

Characterization of Fabry-Perot resonators and their transmitted intensity at the focus of an optical system which collects the output beam emerging from the cavity is analysed in terms of mirror surface irregularities and of fluctuations of the refractive index of the medium filling the resonator. It is pointed out that an amplitude averaging method should be employed in order to correctly describe the system behavior, instead of the intensity convolution procedure commonly used in the literature. Explicit expressions (easy to compute) are derived for the amplitude at the focal point of the optical system from the standpoint of the geometric-optics approximation.
