LASER MACHINING DEVICE

摘要

In order to simplify a configuration even if laser beams of different wavelength bands are used, a laser output device, which oscillates laser beams (L1 and L2) of plural wavelength bands, and an irradiation head (16), which performs irradiation by condensing the laser beams (L1 and L2) of the respective wavelength bands with focal distances thereof being shifted from each other on the same optical axis S, are included.
