ABSTRACT

The present disclosure provides a laser cutting method comprising steps of:
(a) emitting a laser light to a spatial light modulator that has a plurality
of pixels; (b) the laser light modulated by the spatial light modulator being
irradiated on an uncut object, which is to be cut, for forming a focal point
and cutting the uncut object; (c) measuring a cutting depth of the object; (d)
the spatial light modulator converting a phase of each of the laser light
modulated by each of the pixels to change a light pattern distribution at the
focal point when the cutting depth of the object reaches a first predetermined
depth; and (e) repeating the step (b) to the step (d) until the cutting depth
of the object reaches a second predetermined depth; wherein the first
predetermined depth is varied when the step (b) to the step (d) are repeated.
