title: Collimation of emissions from a 1-cm aperture tightly arranged, multistripe laser-diode bar with a multiprism array coupling.
abstract: A total of 100 beams emitted from 100 stripes, with an 80-mum aperture spaced on 100-mum centers, of a 1-cm linear diode array were collimated by a multiprism array consisting of 15 800-mum-wide prismlets. The spatial intensity distributions of each eight-beam unit were rotated 90 degrees through three total reflections in a prismlet. The array of prismlets transforms a long dotted line (a long line array of emitters) to a series of short dotted lines arranged in parallel. Collimated beams were focused to a spot of ~500 mum (FWHM).
