Computer-generated holograms for laser diode (LD) focusing are described. A quantitative description of design tradeoffs is given. The LD parameters (not parallel input light) are included. Multiple CGH lenses, nonequal focal lengths in x and y, positive and negative focal lengths in the same lens, circular focal spots and equal variance focal spots, attention to focusing angles, and 1-D LD array collimation for optical data processing applications are considered.
