Claim Text:
1. A system for combining laser light sources, comprising: a stack of laser diode bar arrays, comprising two or more laser diode bar arrays, each laser diode bar array having multiple laser diodes; a multimode optical fiber; and a plurality of optical elements disposed between the stack of laser diode bar arrays and the multimode optical fiber, configured to direct light from the stack of laser diode bar arrays to the multimode optical fiber, the plurality of optical elements further comprising: wherein at least one FAC lens of the plurality of FAC lenses is misaligned with respect to its corresponding laser diode bar array, wherein a central optical axis of the at least one misaligned FAC lens is translationally or rotationally offset from a beam direction of its corresponding laser diode bar array, and wherein the at least one misaligned FAC lens has at least one of a translational position and an orientation relative to its corresponding laser diode bar array different from another FAC lens of the plurality of FAC lenses relative to the another FAC lens' corresponding laser diode bar array.
