摘要
通过对大功率激光器阵列热现象的分析 ,采用有限元分析法建立了大功率激光器稳态工作时的空间温度分布模型 ,给出了具体的温度分布曲线 ,由此模型得出大功率激光器阵列沿谐振腔方向有一定的温度差 .该模型给出的载体、芯片的温度分布 ,可以指导阵列载体、散热器的设计 ,优化它们的尺寸 .样品的实验数据与模型的理论预测结果吻和得很好 .
A model of temperature distribution is built for high power laser arrays under the thermal analysis of the static working condition by FEM.There is a temperature difference along the cavity's longitudinal direction of the laser according to the calculation results of the model.The distribution of temperature gained from the model gives a certain reference to the design of laser array's submount and cooler.Experimental results from test of the laser diode wavelengths and the test data of the thermal coupler match the theoretical predication well.
