PURPOSE:To branch plural beams of raser light into optional positions by providing the titled device with a shutter to connect/disconnect optionally and independently reflected raser light from an optical means to branch each of plural beams of laser light made incident from the coupler into the reflected part and transmitted part at a required rate, and a means to adjust each reflected laser light so as to give the same optical axis. CONSTITUTION:A light energy coupler 1 is arranged on the 1st fibers 30, 31 and 2nd fibers 32, 33 to branch each laser light transmitted through these fibers to a branch fiber 36. The 1st and 2nd beams of laser light 4, 8 are guided from a concentrically controlled laser light source to these fibers 30, 32. The 1st laser light 4 projected from the 1st fiber 30 collimated by a lens 2 and made incident to the 1st optical means 3, which is composed of five segments 301-305 consisting of filters having different reflection factors. |
