| 摘 要： | 建立在介质内部均匀发热基础上的板条激光器热效应理论与器件实际相差甚大,本文根据介质对光的吸收规律建立介质内部非均匀发热模型,计算与实验结果表明,新的理论模型更接近于实际激光器件。

| Abstract: | The thermal conduction theory based on uniform heating in the slab laser has presented before, but the results obtained from this theory disagree considerably from the results of experiment. In this paper, a non-uniform heating model based on the absorption law of medium is proposed. According to this model, the temperature distribution in the slab laser under CW and pulse pumping is solved. Thermal stress and fracture limitation of the slab are given. The new model is in accordance with the experimental results. |
