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。
In order to enhance the understanding of combustion-driven continuous wave DF chemical lasers, especially to improve the understanding of F atom generation environment and laser lasing environment in the combustion chamber, a series of DF lasers without light were tested. The results show that without the main diluent, the DF laser can also achieve higher power levels and mass-flow power, without the diluent, the output power and specific power will be lost by about half. According to the experimental data, qualitative analysis of the main and secondary diluents on the laser operation. DF chemical lasers can emit light without any diluent, which provides a basis for simplifying laser design.
