The invention relates to a data acquisition and optimization method for laser processing of multiwave group holes. The acquisition method comprises the steps of acquiring by the selection modes of all holes on a conducting surface of UG software and storing a file with the extension name of '.txt'. The optimization method comprises the following steps: (1), opening the stored file with the extension name of '.txt' by using WORD software; (2), performing WORD edition for the first time; (3), performing optimal sequencing; (4), performing optimal operation; and (5), arranging into a processing program file. The invention particularly provides the data acquisition and optimization method for laser processing of the multiwave group holes, which solves the problems of high-efficiency programming and high-efficiency processing of the multiwave group hole processing program, successfully finishes multi-ring wave heat screen micro group holes and high-efficiency laser processing, and has the advantages of high processing efficiency and low cost.
