Abstract
For generation of high brightness laser beams fundamental modes with the largest cross section compatible with the size of the active medium are necessary. Several schemes have been devised both for stable and unstable resonators. Recently we have proposed and experimentally demonstrated for solid- state lasers the feasibility of segmented mirror resonators, which represent, in one sense, a generalization of the concept of phased array diode lasers /1/. This scheme makes use of appropriate linear and two-dimensional masks inserted in a standard stable resonator. The separate emissions of the laser can be phase-locked by diffraction coupling.
