Claim Text:
1. A diode laser apparatus comprising: a plurality of diode lasers situated to emit a beam along a respective initial propagation axis, each beam having an associated fast axis and slow axis, wherein the fast, slow, and initial propagation axes are mutually orthogonal, and the initial propagation axes are parallel and the associated beam slow axes are in a common plane; collimation optics situated to receive the beams propagating along respective initial propagation axes and produce corresponding collimated beams; and a plurality of fixed reflectors situated to receive the collimated beams and to reflect the collimated beams so as to propagate along respective reflected beam propagation axes that are perpendicular to the corresponding initial propagation axes and with an angle between each reflected beam propagation axis and the common plane that is sufficiently small to provide the reflected beams in a close-packed, stacked configuration, such that the reflected beam propagation axes are offset from each other so as to avoid beam clipping by the plurality of fixed reflectors, and the reflected collimated beams have associated mutually parallel slow axes.
