Abstract: 0587788986 The arrangement for combining and shaping the radiation of a plurality of laser diode lines, comprising at least two laser diode lines whose radiation has a cross section in the emission plane (x-y plane) whose longitudinal axis is a multiple of the transverse axis, one collimator unit for each laser diode line, which collimator unit is arranged downstream thereof in the radiation directly, a combining unit for combining the collimated radiation of the individual laser diode lines by a side-by-side arrangement in the direction of the transverse axis, and a recombining unit for dividing the combined radiation in the direction of the longitudinal axes into individual partial beams and recombining the latter by a side-by-side arrangement in the direction of the transverse axes.
