A method and apparatus for delivering laser energy to an object, by: energizing at least one laser energy source having a plurality of at least two spaced, active segments to emit a laser beam from each segment, and to thereby output from the laser energy source a plurality of separate laser beams along respective optical axes initially spaced from each other according to the spacing of the active segments, which beams tend to diverge and thereby to overlap as they progress along their respective optical axes; and at a near-field region of the at least one laser energy source or a region optically conjugative with the near-field region, where the beams are still separated and spaced from each other, laterally displacing the optical axis of at least one of the beams with respect to that of the other before delivering the plurality of beams to the object.
