摘要
基于化学反应的非链式脉冲DF激光器是产生3.5～4.1μm波段的有效相干辐射光源,具有存储能量水平高等优点。这些优点使得该激光器倍受中红外领域激光研究者的重视。为了更好地提高非链式脉冲DF激光器的输出性能,研制高能量水平的DF激光器,本文详细介绍了自引发大体积放电技术、混合气体配比技术、循环冷却技术等DF激光器关键技术,重点介绍了自引发大体积放电技术。这几种技术将为研制高性能DF激光器提供理论指导。
Pulsed non-chain deuterium fluoride（DF） lasers based on the chemical reaction are proper sources of powerful coherent radiation in the 3.5-4.1 μm spectral regions and they have intrinsic ability to store high levels of energy.These advantages make DF laser attractive to researchers in the mid-infrared laser field.In order to effectively improve the output performance of non-chain DF lasers,the key technologies of DF lasers were researched in this paper.The key technologies including self-initiated volume discharge,mixture ratio and recirculating and cooling were introduced.Particular emphasis was put on self-initiated volume discharge.These technologies will provide theoretical guidances for the further research on DF lasers.
