为了减弱激光二极管端面泵浦固体激光器热效应的影响，提高激光谐振腔稳定性及改善激光器的输出特性，以激光二极管端面泵浦Er:Yb:glass/Co:MALO晶体为研究对象，采用有限元分析方法，并根据热传导理论对其进行多物理场耦合热效应分析，系统分析了非键合和键合晶体、泵浦中心波长、功率以及束腰半径对激光晶体的温度场、热应力场以及形变量的影响。结果表明：键合晶体中Co:MALO晶体不仅起到了被动调Q的作用，还起到了热沉的效果，可以有效改善晶体内部的温度分布、热应力和形变量。中心波长为940 nm的泵浦对晶体的穿透性远高于976 nm，采用940 nm的泵浦可以改善晶体的最高温度，但976 nm泵浦结构是扩散键合较安全的结构。由于增大泵浦功率会导致晶体单位面积功率密度分布的增加，热效应也会加剧，泵浦功率增大100 mW对应温度增加9 K，热应力增加1.5 MPa，热形变增加0.5 μm。减小泵浦光束半径也会导致热效应的增加，但影响相较于功率不明显。理论分析结果可为激光二极管端面泵浦铒镱共掺磷酸盐玻璃1.5 μm固体激光器减小热效应的合理优化设计提供数据理论支持。
