摘要：

Laser resonators for active generation of bright Bessel-Gauss fields are designed, which employ aspheric (conventional or diffractive) radially phase-conjugating miners. The planar semi-transparent mirror is located at the waist of the Bessel-Gauss mode, but the second mirror is necessarily aspheric unless an exact Fourier-transform relationship between the fields at the two miners is established with, e.g. an intracavity lens. Conventional Gaussian-beam resonators and Fabry-Perot resonators are obtained as natural limiting cases of pure Gaussian and Bessel modes, respectively, and modal discrimination is studied with the Fox-Li algorithm.
