摘　　要：针对燃烧驱动的连续波DF/HF激光器可靠点火的性能要求,设计制作了氟气(F2)发生器作为新型的点火系统。开展了真空条件下的点火试验,验证不同NF3和H2配比对产物中F2摩尔浓度及平衡温度的影响,重点考察了F2发生器自身点火性能的稳定性和可靠性,进行了F2发生器作为点火系统的实际点火试验。F2发生器能够保证自身点火成功并提供最高含量为42%的含F2混合气体,经过合理的时序控制,含F2混合气体能够高效地点燃激光器增益发生器,在已开展的近百次点火试验中未出现点火不成功的情况。试验验证了F2发生器作为新的点火系统替代常规火花塞点火器的可行性与可靠性。A fluorine gas（F2） generator was designed as a new ignition system to satisfy the performance requirements of the combustion-driven continuous wave（CW） DF/HF chemical lasers which needed to be inflamed reliably. F2 generator tests and actual ignition tests with F2 generator were carried out under the vacuum condition to find the disciplines that F2 mole concentration in the product and the equilibrium temperature of the product changed by the different mole ratio of NF3 and H2, mainly inspecting the F2generator＇s own stability and reliability of the ignition performance. These tests showed that the F2 generator itself could be inflamed reliably and provide F2 gas mixture in which the highest content of F2 was up to 42%. With a reasonable timing control, F2 mixed gas could inflame the gain generator of the laser efficiently. Unsuccessful ignition did not occur in nearly a hundred times actual ignition tests. The tests verified that the new ignition system with F2 generator as a new alternative to conventional spark ignition was feasible and reliable.
