PURPOSE:To enable the discrimination of laser beams under irradiation at present from any laser light source by making all of the hue of corresponding guide beams differ concerning the laser light sources for several work with different wavelengths. CONSTITUTION:The CO2 laser beams 15 and the He-Ne laser beams 16 are overlapped by means of a dichroic mirror 7, and red luminous flux 17 is obtained. The YAG laser beams 18 and green beams 19 are overlapped by means of a dichroic mirror 9, and green luminous flux 20 is acquired. The luminous flux 20 is bent by means of a reflecting mirror 12, and reflected by means of a dichroic mirror 11, the luminous flux 17 and the luminous flux 20 are overlapped, and luminous flux 21 is obtained. When only the first output controller 1 is operated, power is supplied only to the laser light source 3 for the first work and the first guide light source 4. |
