激光切割方法
摘要：
本发明涉及一种激光切割方法。该激光切割方法包括以下步骤：沿第一方向利用激光束照射待加工物件，以在该待加工物件上形成一个第一加热带；对该第一加热带进行冷却，以使该待加工物件沿该第一方向产生一个第一裂纹，该第一裂纹具有一个第一深度；沿与第一方向相交的第二方向利用激光束照射待加工物件，以在该待加工物件上形成一个第二加热带；对该第二加热带进行冷却，以使该待加工物件沿该第二方向产生一个第二裂纹，该第二裂纹具有一个第二深度，且该第二深度大于该第一深度。
摘要（英）：

The invention relates to a laser cutting method, including the following steps: a laser beam is utilized for irradiating an object to be processed along a first direction so as to form a first heating region on the object be to processed; the first heating region is cooled so as to result in the object to be processed to generate a first crackle along the first direction, and the first crackle is provided with a first depth; the laser beam is utilized for irradiating the object to be processed along a second direction which is crossed with the first direction so as to form a second heating region on the object to be processed; and the second heating region is cooled so as to result in the object to process to generate a second crackle along the second direction, the second crackle is provided with a second depth, and the second depth is larger than the first depth.
