ABSTRACT:
An improved coupled waveguide laser array which provides a set of in-phase, phase locked optical beams is disclosed herein. The improved laser array of the present invention includes first and second coupled cavities for providing first and second beams in a first direction, respectively. The first and second cavities have substantially parallel longitudinal axes and apertures at first ends thereof for emitting the first and second beams. A mirror is mounted in a plane transverse to the longitudinal cavity axes and includes a first partially transmissive section mounted in optical alignment with the first cavity. The mirror further includes a first substantially reflective section mounted in optical alignment with the second cavity.
