Abstract
A laser device comprises a plurality of laser diodes, each laser diode emitting a light beam having a fast axis and a slow axis and a beam direction; and one or more optical components configured to modify a divergence of the light beams in a fast axis plane and/or in a slow axis plane such that the light beams have a same focal plane in the fast axis plane and in the slow axis plane.
