Title: Toroidal multipass absorption device

Abstract

A toroidal optical device can include a ring mirror defining a toroidal optical cavity symmetric about an axis and an optical coupler situated inside the toroidal optical cavity. The optical coupler can be situated to direct an input light first received from outside the toroidal optical cavity propagating inside the toroidal optical cavity, to multiply reflect from the ring mirror inside the toroidal optical cavity. A method includes producing one or more additional ring mirrors defining a toroidal optical cavity symmetric about a sagittal axis using a first ring mirror as a master form, and affixing an optical coupler inside the optical cavity to at least one of the one or more additional ring mirrors.
