Abstract
The arrangement focuses a combined laser beam ( ) composed of individual laser beams produced by laser diodes ( ) on a common spot. Prismatic reflecting bodies ( ) are arranged in depressions ( ) provided in a common substrate ( ) between parallel rows (R ,R ; R ,R ) of the laser diodes ( ). Each reflecting body ( ) has oppositely inclined reflecting surfaces arranged on opposite sides thereof for deflection of the individual laser beams from the two adjacent rows of laser diodes. Two cylindrical lenses ( ) are arranged on opposite sides of each reflecting body ( ) between the laser diodes and the reflective surfaces to convert elliptical remote fields of the laser beams into circularly symmetric remote fields. Laterally movable focusing lenses ( ) for each individual laser beam are arranged on the reflecting bodies ( ) between the common spot and the reflecting surfaces for individual adjustment of the laser beams, whereby the combined laser beam ( ) is focussed on the common spot.
