Abstract
A laser machining device includes a plurality of oscillators to emit laser beams having different wavelengths from each other; a machining head to emit laser beams emitted from the respective oscillators to a machining object; a plurality of transmission fibers to transmit the laser beams to the machining head; a wavelength dispersion element; and a focusing lens to superpose the laser beams emitted from the transmission fibers, wherein the wavelength dispersion element is arranged at a position at which the laser beams are superposed by the focusing lens.
