Paper Abstract
High power diode laser arrays need special micro-optic beamshaping to optimize for collimation and spot focusing. A
known and established solution makes use of cylindrical micro- optics for fast axis collimation and subsequent individual
twisting of each emitter beamlet by a micro-optic cylindrical telescope array in order to achieve a symmetric beam
parameter product. A crucial factor for the overall performance is the achievable transmission to collimation and the
fiber coupling efficiency. We present an optical analysis of vignetting effects on the transmission in the beam twisting
setup and show an optimization which can be achieved by advanced micro-optic production technologies.
