Abstract
A device for interleaving a plurality of laser beams (2a, 2b . . . ) that includes laser emitters (3a, 3b, . . . ) arranged along a first direction (X) at a predetermined first distance (P1) from each other to generate laser beams that are aligned parallel and run at a first angle (α) to the first direction (X). Deflecting surfaces (7a, 7b, . . . ) deflect the laser beams so that the deflected laser beams run parallel to one another at a second angle (β). The first angle (α) and the second angle (β) are matched so that the optical path lengths (L1a+L1b, L2) of the laser beams between a first plane (X, Z) running along the first direction (X) in the beam path upstream of the deflecting surfaces and a second plane (B, Z) running along the second direction (B) in the beam path downstream of the deflecting surfaces are identical.
