发明名称 Laser processing method
摘要 A laser processing apparatus has a first laser beam reversal apparatus which reverses the laser beam from the laser oscillator, and a second laser beam reversal apparatus which reverses the laser beam reversed by the first laser beam reversal apparatus, and guides the laser beam to the inside of the processing head, in which a first laser optical path which runs from the laser oscillator to the first laser beam reversal apparatus, a second laser optical path which runs form the first laser beam reversal apparatus to the second laser beam reversal apparatus, and a third laser optical path which runs from the second laser beam reversal apparatus to the processing head are parallel.
