LASER DRILLING DEVICE

摘要

PURPOSE:To provide the titled device changing uniformly both irradiations drilling pitches and making the drilling easily in a zigzag or parallel pattern by irradiating on the traveling material to be worked with dividing a frequency variable pulse laser beam into more than two beams and by making the irradiating position linked and variable. CONSTITUTION:A laser beam 4p is made two vertical beams by a beam splitter 10 and total reflecting mirror 8 and is irradiated on the high speed traveling material 1 to be worked for drilling. With changing the beam frequency both drilling pitches are changed uniformly. Also by changing the distance between the traveling direction of the material 1 to be worked and the solid angle (d) of a horizontal beam 4p and condensing lens 7a, 7b the mutual distance relation L, l of the irradiating position is changed and the drilling is easily made to a zigzag or parallel pattern.
