Abstract
A method of laser beam machining which has a simple construction and which is capable of suitably processing a part to be processed by means of laser beams is provided. A plurality of laser diode arraysare stacked and disposed in such a manner as to allow radiation of laser beams in the direction of a width W of a partto be processed. Each of the laser diode arraysis controlled such that outputsR,L of laser beams with which the partto be processed is irradiated in its width (W)-wise marginal portionsR,L become higher than an outputC of laser beams with which the partto be processed is irradiated in its width (W)-wise central portionC. While the partto be processed is irradiated with the laser beams with the distribution of energy thus changed, the laser beams are displaced relatively in the longitudinal direction of the partto be processed.
