摘要

同步麦克风阵列测量能量沉积沿着激光灯丝的长度在一次射击。由于空气湍流和激光能量波动导致坍塌位置的扩展，导致单次测量与常规的多次平均之间存在明显差异。

Single Shot Axially Resolved Femtosecond Laser Filament Profiles

An array of synchronized microphones measures energy deposition along the length of laser filament in a single shot. A spread of collapse location positions due to air turbulence and laser energy fluctuations causes a pronounced difference between single shot measurements and conventional multi-shot averaging.
