摘要: 用放大法测量了分别在甲苯和乙醇两种液体燃烧驱动下气动CO2激光器的小信号增益系数。实验发现,用甲苯作为燃料时激光器的平均小信号增益系数可达0.62m-1,远远高于乙醇作燃料时的小信号增益系数。结合甲苯和乙醇分别与空气燃烧后产物组分的配比,对实验结果进行了分析,得出甲苯是燃烧驱动气动CO2激光器的一种比较理想的燃料。

Abstract: With the help of amplification method, the small signal gain of a gas dynamic CO2 laser is measured respectively under toluene and alcohol driving conditions.The experiments show that with toluene used as fuel,the small signal gain may reach 0.62m-1,which is by far higher than that with alcohol used as fuel.In conclusion,toluene is an optimum liquid fuel for combustion driven gas dynamic CO2 laser
