Abstract

We demonstrate the phase locking of a 12 X 12 two-dimensional surface emitting laser array to generate 1.4 W of output power in diffraction limited far-field. A phase contrast imaging system is used to measure array element phases and apply corrections to an intracavity liquid crystal array.
