半导体泵浦碱金属蒸汽激光器(DPALs)作为一种新型激光器,综合了半导体激光泵浦技术和碱金属蒸汽工作物质的优点,有望实现高功率、高效率、高光束质量的连续激光输出。通过基于速率方程理论构建的理论模型,对超高功率半导体激光器的运行状况进行了计算机模拟。理论模拟表明,从半导体泵浦碱金属蒸汽激光器获得连续输出百千瓦级激光输出是可行的,并且可以保证很高的斜率效率和很好的光束质量。该种超高功率激光器可以满足航空航天等领域中对超大功率近红外激光光源的需求。
As a new type of laser, semiconductor pumped alkaline metal vapor lasers (DPALs) combine the advantages of semiconductor laser pumping technology and alkali metal vapor working materials and are expected to achieve continuous laser output with high power, high efficiency and high beam quality. Based on the theoretical model constructed based on the rate equation theory, the operating conditions of ultra-high power semiconductor lasers are simulated by computer. Theoretical simulations show that it is possible to obtain a continuous output of one hundred kilowatts of laser output from a semiconductor pumped alkali metal vapor laser, with guaranteed high slope efficiency and good beam quality. This ultra-high-power laser meets the needs of ultra-high-power near-infrared laser sources in aerospace and other fields.
