Abstract
A gain-guided phase-locked semiconductor laser array has been observed to emit a single narrow lobed far-field radiation pattern up to 70 mW, at which power level it exhibits a distinct change. We show that this effect results from a new phase-locked mode attaining threshold; the original mode remains phase locked above this power level.Keywords
