ABSTRACT:
A laser machining method and a laser machining apparatus superior in hole position accuracy and hole quality. An outgoing beam outputted as short pulses is shaped by a pulse shaping unit so as to form a #1 branch beam. The #1 branch beam is supplied to a portion to be machined, so as to machine the portion. In this case, the #1 branch beam may be controlled to synchronize with the outgoing beam. When a piece to be machined is made from a metal material and at least one of an organic material and an inorganic material, the metal material is machined with a laser beam shaped to have a pulse width not shorter than 100 ns, and at least one of the organic material and the inorganic material is machined with a laser beam shaped to have a pulse width shorter than 100 ns.
