PURPOSE:To stably and accurately divide a high output laser beam at low cost by a compact distributor. CONSTITUTION:A lens 12 for introducing a laser beam which diffuses the laser beam 11 for work emitted from an oscillator (not shown in figure) is disposed at a specified distance apart on the incident port side of a kaleidoscope 10. The kaleidoscope 10 is for making the spatial distribution of the laser beam 11 uniform, and a multi-division lens 13 having desired laser division ratio is provided on the exiting port side of the kaleidoscope 10. Then, the uniformized emitted laser beam 11 from the kaleidoscope 10 is divided and condensed through the lens 13 to be introduced to an optical fiber 14. |
