详细研究激光通过光学系统后的分布对深入研究激光与物质相互作用具有重要意义。从任意给定的光束分布出发 ,较详细地考虑了激光的衍射过程 ,研究一个已经获得工业应用的激光变换系统。 A detailed study of the distribution of the laser after passing through the optical system is of great importance for further research on the interaction between the laser and the material. Starting from any given beam distribution, the laser diffraction process is considered in more detail and a laser conversion system that has obtained industrial applications is investigated.
