1. A laser system comprising:
a plurality of beam emitters each emitting one or more beams;
a dispersive element for receiving the beams and combining the beams, in a wavelength-beam-combining (WBC) dimension, into a multi-wavelength beam;
a plurality of collimators disposed optically downstream of the beam emitters and optically upstream of the dispersive element, wherein each collimator receives the one or more beams from a beam emitter and collimates the one or more beams in a non-WBC dimension; and
a partially reflective output coupler for receiving the multi-wavelength beam from the dispersive element, transmitting a first portion of the multi-wavelength beam as an output beam, and reflecting a second portion of the multi-wavelength beam back toward the dispersive element,
wherein optical axes of two or more of the collimators are displaced from each other in the non-WBC dimension.
