PURPOSE:To provide a device for branching laser beam which securely branches the laser light from a laser device through an optical system with simple constitution. CONSTITUTION:The branching device is equipped with a kaleidoscope 13 which has a reflecting surface as its internal surface and is polygonally sectioned, an incidence lens 12 which converges the laser beam and makes it incident on the kaleidoscope 13, a condenser lens 14 which converges respective laser beams branched through the kaleidoscope 13, and plural optical fibers 15 which have incidence end surfaces provided on positions on which the respective laser beams are made incident. |
