摘　　要：研究了一种利用分子筛延长CO2激光寿命的方法,在激光腔内放置分子筛可吸附大量工作气体,当因放电导致CO2浓度下降时脱附释放CO2以保持混合气体的最佳比例,起到稳定输出延长激光器寿命的作用。通过四极质谱仪对激光腔内放电气体进行了定量分析,试验结果证明该技术的可行性。A new method to prolong operation time of CO2 laser was presented. Zeolites are used to absorb a great quantity of fresh gas CO2, and when the concentration of CO2 begins to decrease caused by dissociation in discharge, CO2 gas is released from the zeolites, abating the difference between the real concentration of gases and the optimum one. This is useful to prolong the lifetime of sealed-off CO2 lasers in the working gases deterioration way. Precise measurements were made by using quadrupole mass spectrometer Balzers QMS200. The experimental results prove this new technology to be feasible.
