A Monte Carlo (MC) model was used to simulate ceramic grain growth during laser ablation. The simulation was performed to elucidate the effects of temperature distribution on grain growth. The influence of temperature distribution on the grain growth exponent was also indicated. According to the grain growth mechanism, the grain growth process of Al₂O₃ ceramics with different laser powers (170 W, 210 W, 260 W) and the same time (0.2 s) was simulated. The result shows that ceramic grain growth can be well simulated by the MC method during laser ablation. Particularly, it was observed that grain size was larger in the central region than at the edge, and the laser damage mechanism was microcracks caused by coarse grains. It was also shown that the simulation results were consistent with the experimental results.

蒙特卡洛（MC）模型用于模拟激光烧蚀过程中陶瓷晶粒的生长。进行模拟是为了阐明温度分布对晶粒生长的影响。还指出了温度分布对晶粒长大指数的影响。根据晶粒长大机理，Al ₂ O ₃的晶粒长大过程模拟了不同激光功率（170 W，210 W，260 W）和相同时间（0.2 s）的陶瓷。结果表明，在激光烧蚀过程中，MC法可以很好地模拟陶瓷晶粒的生长。特别地，观察到中心区域的晶粒尺寸大于边缘的晶粒尺寸，并且激光损伤机理是由粗大晶粒引起的微裂纹。还表明仿真结果与实验结果一致。
