对二极管端泵浦 Nd:YLF 板条激光晶体的热应力效应进行了数值研究。理论模型的建立考虑了板条中泵浦光束的发散度和上转换过程中产生的额外热量。利用三维有限元分析，获得基于理论模型的精确数值解。我们的分析重点是 Nd:YLF 板在激光和非激光条件下的热断裂损伤，并将预测值与实验结果进行了比较。
The thermal stress effects of the diode-end-pumped Nd:YLF slab laser crystals are numerically investigated. The theoretical model is established by considering the divergence of the pump beam in the slab and the additional heat generated in the upconversion. Using the three dimensional finite element analyses, accurate numerical solutions based on the theoretical model are achieved. Our analyses focuses on the thermal fracture damage of the Nd:YLF slab under both the lasing and non-lasing conditions, and the predicted values are compared with the experimental results.
