Abstract: With the arrival of the era of intelligent manufacturing, the demand for precision parts processing in various industries is becoming increasingly strong. The laser's own spatial dimension processing system has the ability to regulate the changes in the spatial dimension of the laser beam, which is particularly suitable for efficient and high-precision laser processing. Therefore, it has good application prospects and market demand. The spatial dimension processing system of laser itself mainly includes point dimension, one-dimensional, two-dimensional, three-dimensional, and "5+N" dimensions. The optical structure of laser processing systems from point dimension to "5+N" dimensions is discussed, and the influence of optical lens structure size, installation position, motion mode, etc. on the spatial dimension changes of focused laser beams is analyzed. The influence of optical structure on processing range and accuracy in each dimension processing system is also explored, the main products and their technical parameters in industrial applications for various dimensions of laser processing systems are introduced, and compares the differences in technical parameters between domestic and foreign products. It can provide guidance for the industrial application of various dimensions of laser processing systems, and has a long-term impact on the development of efficient and high-precision laser processing technology.
