Mode discrimination with rimmed optical resonator.

Abstract

A rimmed optical resonator is studied both theoretically and experimentally. It consists of a convex mirror that spreads out the mode volume and an annular concave mirror that controls the diffraction loss. It is found that such a system is definitely superior to a conventional stable resonator for Fresnel numbers larger than unity. It utilizes larger mode… (More)
