Abstract
Multimode, asymmetric, and astigmatic light beam generated by laser diodes and laser diode arrays are the subject of this paper. The exact description of propagation of this type of beams is very important in several applications as: diode pumped solid state lasers, laser diode range finders, laser printers, etc. Developed in this paper is a quasi-geometrical method of transformation of these beams in real, generally asymmetric, optical systems. The inherent property of the asymmetric beam is the appearance of the pair of astigmatic foci after passing through a focusing lens. This effect can be corrected for single mode beam, but in the case of multimode beam generated by laser diode array it becomes the main drawback difficult to remove. A few examples are presented of transformation of these beams in real optical systems including spot diagrams of astigmatic foci for typical cases.
