    • The present invention is to provide a laser machining method for performing an ablation process with laser beams which are longer wavelength than the absorption edge of a material for forming a workpiece without cracks even if the repetition frequency of the pulse laser beams is set over 20 kHz. The laser machining method is to perform the laser process by irradiating the pulse laser beams with the 20 kHz or more of the repetition frequency to the workpiece. Processing conditions are set by an experiment for obtaining the pulse width which does not cause the cracks with the laser beams based on the wavelength of the absorption edge of the workpiece. The wavelength of the pulse laser beams is the Y-axis, and the pulse width is the X-axis When the relation between the each wavelength and the critical point of the pulse width is plotted on a graph, the wavelength of the pulse laser beams is the Y-axis, and the pulse width is the X-axis. In order to perform a laser machining process, the pulse laser beams in a section under a curved line formed by connecting the critical point of the pulse width at the each wavelength are used.

    • 本发明提供一种激光加工方法,即使脉冲激光束的重复频率设定为20kHz以上,激光束的波长比用于形成工件的材料的吸收边缘波长更长的激光 。 激光加工方法是通过将20kHz以上的重复频率的脉冲激光照射到工件来进行激光处理。 通过用于获得基于工件的吸收边缘的波长的激光束不会引起裂纹的脉冲宽度的实验来设置加工条件。 脉冲激光束的波长为Y轴,脉冲宽度为X轴当脉冲宽度的每个波长和临界点之间的关系绘制在曲线图上时,脉冲激光束的波长 是Y轴,脉冲宽度是X轴。 为了进行激光加工处理,使用通过连接各波长的脉冲宽度的临界点而形成的弯曲部下方的脉冲激光束。 (附图标记)(AA)波长; (BB)脉冲宽度
