The core principle of non-destructive laser cutting is laser thermal stress controlled fracture technology, which uses laser to locally heat the material and produce a temperature gradient on the material surface, so as to induce the generation of thermal stress, and induce the stable fracture of the material through appropriate control of thermal stress. Non destructive laser cutting can realize low-temperature processing and avoid the ablation damage of solar cells.
