摘要: 为了提高抽运效率、改善抽运均匀性、克服热退偏的影响,建立了一套V型有源镜构型热容激光器,采用数值模拟与实验研究相结合的方法,对激光介质热分布进行了研究。数值模拟充分考虑了内热源的分布不均匀性,分析了激光介质的3维热分布。实验中采用热像仪对激光介质的表面温度进行了无接触测量。数值计算和实验研究结果具有较高的一致性。研究结果表明,该激光器构型对于提高热分布均匀性有较大的帮助。Abstract: In order to improve the pumping efficiency and make the temperature distribution more uniformity, a V-shape active mirror heat capacity laser was set up.Heat distribution of the laser medium was studied with numerical simulation and experimental methods.In numerical simulation, asymmetry of inner heat source was sufficiently considered, and in three-dimension heat distribution was analysed.In experiment, the temperature on the surface of the laser medium was measured by a thermal imaging system.The result of numerical simulation and experimental measurement were quite identical.It is demonstrated that the shape of the heat capacity has great advantage on improving thermal distribution.
