Abstract :
Above-threshold analysis of ARROW-type diode lasers is performed for the first time. One key finding is that preferential pumping of the antiguide core dramatically enhances the single-mode power, in good agreement with experiment. Single-spatial-mode operation in a stable beam can be maintained to >10x threshold from large-aperture (6-20 μm) devices
