Abstract
An optically stacked, laser diode array module (10) includes a mounting block (100) having a series of stepped, parallel diode mounting surfaces (101) on one face of the block, each diode mounting surface cooperating with a respective pair of reference surfaces (102, 103) of the block to form a respective outside block corner, a series of laser diodes (300) affixed to the block, with facets of the diode aligned with the reference surfaces forming the outside block corner with the mounting surface on which the diode is disposed, such that a corner of each diode is aligned with a respective corner of the block, and a beam reflector (200) secured to the block and having a series of stepped, parallel surfaces, each positioned to intercept and reflect a respective one of the beams (500) from the laser diodes, such that the reflected beams are parallel and stacked. The beams (500) emitted from the laser diodes (300) can be collimated by microlenses (400).
