Abstract
Devices and methods for cutting an opening from a workpiece. The apparatus comprises a first emitter and a second emitter, a power of a first laser emitted by the first emitter being smaller than a power of a second laser emitted by the second emitter. The apparatus further comprises a laser head, an image sensor, and a processing unit. The laser head is coupled to the first and second emitters and adapted to move adjacent to a first side of a workpiece and direct the first and second lasers onto the first side. The image sensor is configured to receive the first laser to form an image of the first laser. The processing unit is configured to determine a difference between a profile of the image of the first laser and a predetermined profile of an opening to be cut from the workpiece.
