Anamorphic beam concentrator for linear laser-diode bar.
An anamorphic beam concentrator for linear laser-diode (LD) bar is presented. It consists of a tapered SiO(2)-rod with skewed and curved surface. The principle and applicability of this device are numerically investigated by ZEMAX and experimentally illustrated for the specific example of the linear LD bar. Results show that a relative symmetrical output beam spot is produced at the output facet of the rod and the intensity and spatial fluctuations in the input beam are compensated at distance of 20cm from the output facet.
