Abstract

The amplification behavior of a laser pumped cylindrical dye cell located within an axicon reflector has been studied. Compared with a conventional, transversely pumped rectangular amplifying dye cuvette, the axicon shows similar high gain and enhanced beam quality as a result of its radially symmetric excitation geometry. This latter property was experimentally confirmed by a 30% reduction of the divergence of a seed beam after amplification and by increased second harmonic generation conversion efficiency.
