连续波DF化学激光器无稀释剂实验及其分析

为了增强对燃烧驱动连续波DF化学激光器的理解,特别是为了提高对燃烧室中F原子产生环境和光腔内激射环境的认识,进行了一系列DF激光器无稀释剂条件下的出光实验。结果显示,无主稀释剂条件下,DF激光器同样可以达到较高的功率水平和质量流比功率,无副稀释剂条件下,输出功率和比功率将损失一半左右。根据实验数据,定性地分析了主、副稀释剂对激光器运转的影响。DF化学激光器能够在无稀释剂条件下出光,为简化激光器设计提供了依据。

Experiment and Analysis of Continuous Wave DF Chemical Laser without Diluent

To enhance the understanding of combustion-driven continuous wave(CW)DF chemical lasers,especially for knowing the situation of the generation of F atoms in combustion chamber and the excitation situation in the optical cavity,a series of experiments is carried out without diluent.The results show that,DF lasers will be in good condition without primary diluent,and lose a half of power and specific power without secondary diluent.The effect of diluents on lasers is discussed based on the results.DF lasers can run stably without diluent,which provides the evidence for the simplification of DF lasers.
