    • 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.
    • 激光加工方法和激光加工装置,其孔位精度和孔质量优异。 作为短脉冲输出的输出光束通过脉冲整形单元成形,从而形成#1分支光束。 将#1分支光束供给到要加工的部分,以便加工该部分。 在这种情况下,可以控制#1分支光束与输出光束同步。 当要被加工的零件由金属材料和有机材料和无机材料中的至少一种制成时,金属材料被加工成具有不小于100ns的脉冲宽度的激光束,并且至少一个 的有机材料和无机材料用激光束加工成具有短于100ns的脉冲宽度。
