Abstract

PURPOSE:To treat the composed flux of light with an anamorphic optical system by arranging the p-n junction of a semiconductor laser in parallel with a polarizing beam splitter and by arranging a 1/2 wavelength plate between one semiconductor laser and the polarizing beam splitter. CONSTITUTION:The lights from two semiconductor lasers 1 and 5 are overlapped by a beam splitter 4 and are forcused upon a focal plane 9 by means of condensing optical systems 7 and 8. The respective p-n junctions of the lasers 1 and 5 is arranged in parallel with the splitter 4 such that the polarizing plane is turned at 90 degrees between the laser 1 and the splitter 4. By the actions of the lenses 7 and 8 constituting the anamorphic condensing optical system, a generally round spot 10 can be formed on the focal plane 9.
