1. A device for processing an input light beam comprising at least one optical pulse having an original duration, the processing device configured to form the input light beam into a predetermined shape, the processing device comprising:
an optical input for receiving the input light beam;
a stretching device configured to temporally elongate a duration of the optical pulse by spectral spreading of the input light beam and propagate a temporally stretched radiation;
a compressing device configured to at least partially restore the original duration of the optical pulse;
an optical output, arranged downstream of the compressing device, configured to propagate an output beam; and
a shaping device, comprising at least one multi-plane converter located upstream of the compressing device, the shaping device configured to process the temporally stretched radiation and form the output beam into the predetermined shape.
