| 摘 要： | 建立了二极管侧面泵浦板条激光介质模型，给出了相应的热传导方程，应用有限差分法对热传导方程进行求解，得出了介质内的温度分布。分析了不同吸收系数下以及采用单、双侧泵浦时介质吸收的光强分布及温度分布，并讨论了在单、双侧泵浦条件下，泵浦功率变化对介质温度分布的影响。结果表明采用双侧泵浦更利于获得均匀的温度分布，泵浦功率增大时热效应将显著增大。

| Abstract: | The diode side pump model of solid slab laser is established.The temperature distribution is given out by solving the thermal conduction equation with finite difference method.The absorbed light power and temperature distribution inside the medium with one side-pump and two side-pump are studied respectively.And the influence of pump power on the temperature distribution is also discussed.The results show that homogenous temperature is easier to obtain with two side-pump model and the thermal deformation increases with the increasing pump power. |
