摘要：

Numerical simulations of nonlinear pulse propagation in air show an initial pulse formed, absorbed by plasma generation, and subsequently replenished by power from the trailing edge. Here we show that this scenario implies that the length scale for filament propagation is relatively insensitive to the peak input power beyond the threshold for filament generation.
