Disclosed is a laser system that comprises a laser source adapted to emit a laser beam, wherein the laser source comprises a plurality of emitters for emitting respective beam contributions to the emitted laser beam; and first and second feedback means adapted to provide optical feedback to respective first and second parts of the emitted laser beam. The first feedback means is adapted to predominantly feed back a respective angular/directional contribution of each of said beam contributions into a corresponding one of the plurality of emitters from which said angular/directional contribution was emitted at a predetermined output angle, to cause each of the plurality of emitters to predominantly emit a beam contribution towards the second feedback means at an angle corresponding to the predetermined output angle.

Segmented diode laser system

Disclosed is a laser system comprising: A laser assembly () comprising a plurality of emitters; first and second light feedback devices () forming respective external cavities with the laser assembly; a dispersive device () for redirecting respective portions of the light from the laser assembly to the first and second feedback devices (), wherein the first feedback device () is adapted to reflect a feedback portion of the redirected beam back onto the dispersive device () and to generate the output beam () from an output part of the first redirected beam, &#x2014;an imaging device () for generating an optical Fourier transform of the plurality of emitters at a Fourier plane (). The dispersive device () is positioned displaced from said Fourier plane () by a predetermined displacement (d) in a direction along said principle axis ().
