A system for transmitting the spatial profile of laser beams with particular applicability to coherently combine laser beams into one beam. The system includes a tapered waveguide with an inlet and outlet at ends of two waveguide elements each having a reflective surface facing into the waveguide. The reflective surfaces are non-parallel such that the inlet height is different than the outlet height, e.g., inlet height greater than outlet height. The system includes a beam input assembly controlling phases of laser beams input at the waveguide inlet, and the phases of the beams are locked to a substantially single phase. The waveguide length is selected to produce at the waveguide outlet a coherently combined laser beam from the input beams. The beam input assembly includes a laser beam source, a beam splitter generating lower power beams from source beams, and phase adjusters for controlling the phase of each input beam.
