Astigmatic telescope for lasers with an annular gain medium cross section
Abstract
This paper proposes a novel method for excitation of laser gain media having annular cross sections that involves use of a new type of an astigmatic telescope for transforming the shape of the cross section and radiation polarization. Applications to external devices, resonator alignment, and, resonators having a large effective length are described.
