摘要： A multi-laser module includes two compartments arranged one above the other. The lower compartment includes four lasers and four corresponding beam-steering mirrors arranged to direct corresponding laser beams into the upper compartment. The upper compartment includes a regular pentagonal prism and four other beam-steering mirrors each arranged to receive one of the laser beams and direct that beam to the prism. The beam prism has three dichroic-coated surfaces and two antireflection-coated surfaces. Each of three of the beams enter the prism via a corresponding one of the dichroic-coated surfaces. The fourth beam enters the prism via one of the antireflection coated surfaces, and all of the beams exit the prism via the other antireflection coated surface along a common path.
