摘　　要：目前CO_2激光器是被广泛应用的一类气体激光器,然而其运行期间激光腔内工作气体发生等离子诱导化学反应,使CO_2解离成CO和O_2,并产生对激光器有害的成分,致使激光器输出功率逐渐下降。采用催化方法,利用固体催化剂使CO再复合成CO_2是一种高效、低成本的应对激光功率下降的策略。本文描述了CO_2激光器的工作原理及其存在的问题,简要综述了国内外封闭式CO_2激光器用固体催化剂的研究现状,并重点展望了纳米Au催化剂在CO_2激光器中开发应用的前景,为高效、长寿命封闭式CO_2激光器用催化剂的研制和开发提供了新思路。The CO_2 laser is a kind of widely used gas laser,but during the running time its working gas happened easily the plasma induction which lead to the chemical reactions and produce harmful ingredients,mainly were CO and O_2,therefore the output power of CO_2 laser decreased gradually. The catalytic method to eliminate harmful components such as CO is a high efficiency and low cost strategy to deal with the decline of the laser power. This paper describes the working principle of CO_2 laser and the existing problems,and briefly summarizes the domestic and international research status of solid catalyst for CO_2 laser.Moreover,it focus on the prospects of the nano-Au catalysts in the application of CO_2 laser,and provides a new idea for the research and development of solid catalyst for efficient closed CO_2 laser.
