摘要
建立了侧面抽运板条激光器的热力学模型,对千瓦级侧面抽运Nd:YAG板条激光器的温度和应力进行了数值模拟,并对结果进行了分析。在抽运平均功率3890 W时,侧面抽运Nd:YAG板条激光器获得了1012 W平均功率输出,斜率效率约31%,光-光转换效率约26%。测量了板条侧面的温度,与数值模拟结果吻合较好。
The thermodynamic model of side pumped slab laser was established.By numerical simulation,the temperature and the thermal stress of kW-class side pumped Nd：YAG slab laser was obtained.These results were analyzed.In the condition of 3890 watts′s average pump power,the average output power of side pumped Nd：YAG slab laser was achieved to 1012 watts,with slop efficiency of 31% and optical to optical efficiency of 26%.The temperature of slab′s side was measured and accorded well with the simulating results.
