Abstract
A dual-substrate dichroic beam combiner includes two substrates, and a dichroic thin-film filter coated at a nominally planar interface between the substrates. The filter is configured to combine, into a combined laser beam, two input laser beams that are incident on the filter of the combiner from opposite respective sides thereof. One input beam is transmitted by the combiner, while the other input beam is reflected. The substrates are configured to, when heated by absorption of the input laser beams in the filter, form a lens for each of the input laser beams. The lens is either (a) a negative lens for each of the input laser beams or (b) a positive lens for each of the input laser beams. The combiner thereby reduces or eliminates focusing discrepancies between the two input beams, in the combined beam, as compared to a conventional single-substrate dichroic beam combiner.
