Abstract:

Subject of study. Computer simulation of the propagation of laser radiation using the ZEMAX program. Aim of study. Development of a macro written in the Zemax programming language, designed to obtain the intensity distribution in the longitudinal section of a focused laser beam. Method. The developed macro uses ZEMAX functions based on integral transformations, which make it possible to obtain the results of modeling the processes of radiation propagation through optical systems. Main results. The macro written in the Zemax programming language has been developed for analyzing the intensity distribution in the longitudinal section of a laser beam,. The presented macro is used to analyze the propagation of a laser beam, which is affected by aberrational distortions of various types. The results of the macro operation and their analysis are given. Practical significance. The proposed macro allows you to expand the standard capabilities of ZEMAX and can be useful in analyzing the process of laser radiation propagation. The presented results of the macro show the possibility of its application to analyze the effect of various aberrational distortions on the parameters of laser beam focusing in the volume of a transparent material subjected to laser processing. Therefore, a macro can be useful for controlling the spatial distribution of intensity in a focused laser beam with high accuracy in order to ensure maximum processing efficiency of the material being modified.
