Abstract
We describe a novel phase-sensing and control system, based on phase-c ontrast imaging, operating within a linear external cavity laser consi sting of 18 GaAlAs edge-emitting gain stripes. The system is used to a chieve single-spatial-mode operation and diffraction-limited output fr om the linear cavity, which uses diffractive coupling at a Talbot plan e to achieve coherent operation.
