摘要： A method and device for coherent addition of semiconductor laser emission, in particular for use in telecommunications. Individual emitters are coupled, each emitter to some extent experiencing some of the emission of all the others. Rather than all emitting independently of one another, the emitters are arranged in a common resonator. Using an optimization method, e.g., the simulated annealing method, the shape of the resonator mirror may be optimized until it optimally fulfils a preassigned set of mathematical requirements which constitute a set criterion. The individual emitters in the form of individual diodes, a diode matrix or a diode bar are arranged between two or more mirrors. At least one of these mirrors has a special, non-spherical surface that forms an internal correction element. Alternatively, the mirrors may be spherical-shaped with at least one non-spherical phase plate arranged in the resonator beam path. Outside the resonator a further system that includes a generator and a secondary beam shaper transforms the emitted beam so that it has the desired amplitude distribution and phase distribution and the desired irradiance.
