摘　　要：开展了分子筛对非链式电激励重频HF激光器中基态HF分子吸附技术研究,设计了新型的分子筛吸附装置,进行了大量的吸附实验,结果表明:3A分子筛为有效的吸附剂,实现了HF激光器在50 Hz/20s条件下运行时平均激光能量下降率小于5%,大大提高了激光能量的稳定性,延长了激光介质的使用寿命。开展了激光器工作于不同频率条件下使用3A型分子筛吸附装置时的激光能量情况研究,并通过实验方法获得了3A型分子筛的再生活化方法。Based on the previous research,the study of the molecular sieve absorption technology for ground-state HF molecules in non-chain discharge-pumped high frequency HF laser was carried out,a new molecular sieve device was designed and a large number of absorption experiments were finished.The experiment results show that 3A molecular sieve is an effective sorbent to the ground-state HF molecules and using 3A molecular sieve absorption device could make the average HF laser energy reduction rate less than 5%when the laser was operating under 50 Hz/20 s,and 3A molecular sieve can greatly improve the stability of the laser energy and prolong the lifetime of HF laser media.The laser energy reduction rate was studied when the laser was operating under different frequencies with 3A molecular sieve absorption device.In addition,the method of activating treatment of 3A molecular sieve was obtained by experiments.
