论文摘要
使用条纹摄像头，我们直接测量了从自种丝中的N2+发射的时间和空间分辨动力学。我们即使在环境条件下也观察到超荧光的特征特征，并表明发射光的时机沿灯丝的长度变化。必须考虑这些效果，以便对空气中的光细丝进行准确的建模，并且可以利用以设计空气激光中光发射的时间概况。
Using a streak camera, we directly measure time- and space-resolved dynamics of N2+ emission from a self-seeded filament. We observe characteristic signatures of superfluorescence even under ambient conditions and show that the timing of the emitted light varies along the length of the filament. These effects must be taken into consideration for accurate modelling of light filaments in air, and can be exploited to engineer the temporal profile of light emission in air lasing.
