This invention provides a single-row scribing simulation method and a multi-row scanning simulation method based on pulse-by-pulse ablation. These methods address the technical problem of existing pulsed laser processing simulations, which require consideration of the historical dependencies between pulses during global pulse-by-pulse calculations. This results in computation time increasing linearly or even non-linearly with the number of pulses, making them unsuitable for simulating ablation involving hundreds of thousands or even millions of pulses in actual processing. The single-row scribing simulation method and multi-row scanning simulation method provided by this invention decouple global pulse-by-pulse calculations into discrete, locally refined calculations. While ensuring computational accuracy, this significantly reduces the iterative solution range and the number of iterations, substantially lowering the computational dimensionality and time, achieving an order-of-magnitude improvement in computational efficiency.
