| 英文摘要 | PURPOSE:to perform powerful light synthesis by providing focal anamorphic optical systems between lasers and a splitter at the time of letting the light emitting faces of a plurality of semiconductor lasers optically intersect perpendicularly, disposing a polarizing beam splitter at the point of their interections and superposing the plural luminous fluxes. CONSTITUTION:The beams from mutually perpendicularly intersecting semiconductor laser 4, 5 are collimated with colimator lenses 6, 7 and the widths in one direction of the beams are expaneded by anamorphic aocal converters 8, 9 composed of cylindrical beam expanders 8, 9. Next, the beams ar entered to a polarizing beam splitter 10, by which the beam of the laser 5 is perfectly transmitted and the beam of the laser 4 is reflected, whereby the combined light beam A is provided. Thereafter the beam A is deflected with a deflector 11, and is imaged on a recording face 13 by an imaging lens 12. In this way, the light spot is converged, and the resolving power to the recofring face 13 is enhanced. |
