对以D2为燃料、NF3为氧化剂的纯化学燃烧驱动的HBr化学激光进行了研究。抽运反应为H+Br2 → HBr(v≤6,J)+Br，氢原子由F+H2→HF+H反应提供，氟原子则由D2/NF3混合气体燃烧热解生成，激光提取所需的低温低压和快速流动条件由超音速流动系统完成。对由全反反射镜和部分反射(98%)输出镜组成的稳定腔进行了能量提取，获得了P2(4)、P2(5)、P3(5)和P3(6)的稳定激光输出，最大激光输出功率为14.3 W。

The purely chemical combustion-driven HBr chemical laser has been studied using D2 as fuel and NF3 as oxidant. The pumping reaction is H+Br2→HBr(v≤6,J)+Br. Hydrogen and fluorine atoms are produced by the reaction of F+H2→HF+H and burning D2/NF3 mixtures, respectively. And a supersonic flow system provides conditions of low temperature, low pressure and fast flowing to satisfy the need of laser extraction. The stable laser output at P2(4)、P2(5)、P3(5) and P3(6) with the maximum output power of 14.3 W is obtained, when we extract energy from the stable cavity consisted of a totally reflection mirror and a partially reflection mirror (98%).
