title: Large-size Gaussian mode in unstable resonators using Gaussian mirrors.
abstract: Gaussian modes with large sections have been experimentally produced in Cassegrain resonators using Gaussian reflectivity convex couplers. The far field of the beam, which was coupled through a Gaussian coupler, was found to be free from secondary rings.
