摘要：
Twelve beams emitting from twelve stripes, with 200-mu m apertures spaced 800 mu m apart, of a 1-cm linear diode array were collimated by a multiprism array consisting of fourteen 800-mu m-wide prismlets, The spatial intensity distribution of each beam was twisted around its optical axis through three total reflections in a prismlet, transforming a series arrangement of emitters into a parallel arrangement to prevent overlap of adjacent beams. Collimated beams were focused to a spot of similar to 200 mu m (FWHM).
