Laser simulation control method and system

Abstract

The invention relates to a laser simulation control method which comprises the steps of: constructing a three-dimensional simulation model according to the internal structure of a simulation laser andthe material thermal induction value of a part related to the internal structure; inputting simulation data into the three-dimensional simulation model to obtain a simulation three-dimensional pseudo-color image, obtaining a target area exceeding a set stress threshold from the three-dimensional pseudo-color image, adjusting the temperature of the target area of the simulation laser to enable thestress value of the target area to be lower than a set stress threshold value, and taking the adjusted temperature of the target area as a balance temperature; arranging a bidirectional semiconductortemperature controller in a target area, corresponding to the simulation laser, of the test laser; and adjusting the heating or cooling of the bidirectional semiconductor temperature controller according to a temperature distribution color diagram, judging whether the temperature of the target area of the test laser is at a balanced temperature or not, and if yes, completing the control of the test laser. The pointing stability of laser beams output by the laser is improved.

technical field [0001] The invention relates to the field of laser processing equipment, in particular to a laser simulation control method and system. Background technique [0002] In the application of precision micromachining, the laser beam must be accurately and stably incident into the laser scanning and focusing optical system. After beam transformation and shaping, it can be accurately injected into a specific position of the material to be processed, and the local ablation of the material by laser light energy can be completed. . Therefore, the laser beam pointing stability is particularly important. [0003] The factors of laser beam pointing stability include random changes in ambient temperature, and the mechanical structure of the laser will undergo different degrees of thermal deformation at different temperatures, that is, the heat generation of each component is different or the coefficient of thermal deformation is different, resulting in heat generation be...
