Claim 0:
1. A laser processing system equipped with a processing laser beam irradiation device configured to irradiate a processing object with a processing laser beam and perform ablation processing, the laser processing system comprising:
a camera configured to obtain an ablation image of a processed portion of the processing object based on scattered light from the processed portion during processing of the processing object with the processing laser beam; and
a processor programmed to estimate an ablation volume by inputting the ablation image into a deep learning model that specifies a relationship between the ablation image and the ablation volume and outputs the estimated ablation volume,
wherein the deep learning model has been trained by outputting a processing parameter based on the input ablation image, and applying a loss function to the deep learning model based on actual values of the processing parameter, and the deep learning model estimates the ablation volume based on the processing parameter.
