Paper Abstract

The problem of reaching diffraction divergence in annular lasers is extremely complex, and, at this time, is quite far from being solved. The following paper considers traditional attempts of solving this problem, based upon the usage of AXICON optics, as well as some of the newer ways. The three main approaches that will be looked at use resonator unstable in azimuthal direction, astigmatic transformation of annular cross section along with polarization, and the idea of coherent self-imaging in annular geometry.
