摘要: A simple theory is developed for optical resonators, in which the mirrors are each composed of two planes forming a nearly straight dihedral angle and an equivalent beam-waveguide comprising sequence narrow prisms. Geometric considerations yield variation intensity within resonator manner analogous to (although not entirely as satisfying in) case spherical mirror resonator. Modes continuous medium, identified limit particular sequences closely spaced weak prisms, characterized by parameter Ω, found terms Airy functions. An appropriate spot size given [Ω/2k02]⅓, where k0 wavenumber.
