- 1 - ABSTRACT OF THE DISCLOSURE An injection laser of the multilayer planar type, such as, heterostructure GaAs:GaAlAs lasers are provided with offset geometry in the configuration of a current confining structure on the surface of the device to stabilize the propagating optical beam such that the power output versus current pumping characteristic is linear over an extended range of operating currents. The same offset geometry may also be provided in a channel of the substrate to provide additional or alternate means for stabilizing the propagating optical beam.
