Abstract

Abstract

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.
