摘要：
A laser casting apparatus includes a laser light source, a phase disturbing device for disturbing a phase of laser light output from the laser light source, and a beam forming device for forming a beam of a predetermined shape. The formed beam is cast on a work after decomposing the laser light in to beams each having a small area and then superposing the decomposed beams. The phase disturbing device disturbs the phase of the light in a manner so that the superimposed beam formed of the decomposed beams has a uniform energy distribution without interference fringes.
