Embodiment Construction

[0021] like figure 1 , figure 2 As shown, during laser processing, before turning on the high-power stacked laser, it is necessary to indicate the exact position of the stacked spot, so that the processing can be carried out accurately. The present invention adopts the method of installing indicating light sources with the same or different wavelengths on both sides of the stack to realize the determination of the spot position of the stack and the judgment of positive and negative defocus. The specific implementation is as follows:

[0022] The two indicating light sources are respectively installed on both sides of the stack, so that their beams intersect at the focal point of the stack laser after passing through the same optical shaping module as the stack laser. If the light spot of indicating light source a does not coincide with the light spot of indicating light source b, it means that the object to be processed is not at the focal point of the array of light spots, ...
