Abstract: An apparatus includes a dichroic combiner array configured to combine multiple input optical beams and generate an output optical beam. The dichroic combiner array includes multiple mirrors and multiple dichroic filters. A first mirror is configured to reflect a first input optical beam towards a first dichroic filter, which is configured to combine the first input optical beam and a second input optical beam. A second mirror is configured to reflect a combined optical beam from the first dichroic filter to a second dichroic filter. A last dichroic filter is configured to generate the output optical beam. The apparatus also includes a beam dump array having multiple beam dumps configured to terminate stray optical energy. The stray optical energy includes at least one of: (i) optical energy reflecting from at least one of the dichroic filters and (ii) optical energy transmitted through at least one of the dichroic filters.
