Laser Storage Ring (Laser Ring Resonator with Gain Using Total-Internal-Reflection Toroidal Mirrors)

Abstract

Concept is described on Laser Storage Ring (LSR), or the laser ring resonator composed of toroidal mirrors which have an optical function combining focusing and bending function, plane mirrors and gain mediums. LSR is expected to be a powerful laser beam source useful for such applications as the H^- laser stripping or the laser-Compton-scattered gamma-ray beam source. Experimental results are described to show that a laser ring resonator can be composed using toroidal and plane mirrors. It is also shown that the longitudinal resonance function of the ring resonator is basically same as that of the Fabry‒Perot resonator. LSR using total-internal-reflection toroidal mirrors are proposed.
