title: Very large-core, single-mode, gain-guided, index-antiguided fiber lasers.
abstract: Lowest-order, single-mode laser oscillation is reported in gain-guided index-antiguided fiber lasers having core diameters from 100 to 400 microm. A model is presented explaining how to select resonator mirrors to assure single-mode operation.
