<p><P>PROBLEM TO BE SOLVED: To reduce speckle on the emission face of an optical fiber by connecting light from a laser light source to the optical fiber without waste, and reducing coherence of the laser light source. <P>SOLUTION: The apparatus includes: the laser light source 1 that supplies coherent light; a light splitting means composed of one or more beam splitters 2 and 4 and one or more total reflection mirrors 3 and 5, and used for splitting a luminous flux from the laser light source 1 into a plurality of luminous fluxes along the emission light axis of the light source; an optical fiber 8 for uniformizing an incident luminous flux; and a condenser lens 6 by which a plurality of luminous fluxes output from the light splitting means are condensed on the incident face of the optical fiber 8 at different angles. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
