Claim 0:
1. A light-source device comprising:
a plurality of light emitters; and
a plurality of optical elements through which laser beams emitted from the plurality of light emitters pass,
the plurality of optical elements including:
a plurality of first optical elements each to emit a laser beam of a first divergence angle; and
a plurality of second optical elements each to emit a laser beam of a second divergence angle smaller than the first divergence angle,
wherein the plurality of first optical elements is disposed closer to a center of the plurality of optical elements than the plurality of second optical elements, and divergence angles of the plurality of optical elements vary monotonically from an optical element at the center of the plurality of optical elements to an optical element at an edge of the plurality of optical elements,
the plurality of optical elements constitutes a single integrated optical element array,
the plurality of first optical elements forms a two-dimensional array,
the plurality of second optical elements forms another two-dimensional array, and
the another two-dimensional array of the plurality of second optical elements is disposed outside the two-dimensional array of the plurality of first optical elements away from the center of the plurality of optical elements.
