Abstract
We present a geometrical optics analysis of a novel laser cavity with conical mirrors (reflective axicons). A further two dimensional study of the cavity is carried out through formal diffraction theory. We will show that the profile of the modes of such resonator are approximately Bessel-Gauss beams. The design also supports higher order modes, however these turn out to be unstable when perubations are present, they eventually decay to the lowest order mode. An explanation for the Bessel structure is due to the conical nature of the wave-front induced by the axicons, while the bell-shaped profile arises from the finite extent of the cavity.
