摘要

摘要: 基于化学反应的非链式脉冲DF激光器是产生3.5~4.1 m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。

Abstract: 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 m 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.
