千瓦级二极管激光侧面抽运Nd:YAG板条激光器
Diode Laser Side Pumped kW-Class Nd:YAG Slab Laser
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。
Abstract
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.
