ABSTRACT:
A laser light source in which a couple of light beams whose shapes are re-formed and whose polarizing planes are made perpendicular to each other are synthesized by a beam splitter and then the synthesized light is incident on an optical guide through a predetermined optical system, thereby generating the synthesized light having a short spot diameter and an improved power density.
