研究了大气压下飞秒激光诱导等离子体（FLIP）对CH（4）/O（2）/N（2）预混火焰稳定性的影响。改变激光能量、激光重复频率、当量比和O（2）/N（2）共混物中氧的体积百分比。我们的研究结果表明，火焰吹离速度是这些参数的函数。实验发现，有FLIP的火焰吹离速度比没有FLIP的火焰吹离速度增加两倍。高重复频率、大能量激光诱导等离子体火焰稳定作为一种非侵入式的光学火焰稳定技术，可能成为任何燃烧室的一种可行的替代方案。
The influence of femtosecond laser-induced plasma (FLIP) on the stability of a premixed CH(4)/O(2)/N(2) flame is investigated at atmospheric pressure. The laser energy, laser repetition rate, the equivalence ratios, and the volume percentage of oxygen in O(2)/N(2) blends are varied. Our findings indicate that the flame blow-off velocity is a function of these parameters. It has been experimentally found that the flame blow-off velocity increases by a factor of two with FLIP than without FLIP. A high-repetition-rate and a great energy laser-induced plasma flameholding, as a non-intrusive optical flameholding, may be a feasible alternative for any combustor.
