ABSTRACT:
A laser which contains a substantially planar waveguide wherein the waveguide along the direction of light propagation is comprised of varying combinations of high-gain and low-gain regions so that the cumulative gain from one end of the optical cavity to the other varies as a function of position along a line within the plane of said waveguide which is perpendicular to the direction of light propagation.
