论文摘要
在一次镜头中，我们测量了完整的繁殖路径，包括高功率飞秒激光脉冲在空气中传播的高功率飞秒激光脉冲的演变。该技术可以单次检查以射击为基础波动的参数的效果，例如脉冲能量，脉冲持续时间和空气湍流诱导的折射率扰动。我们发现，即使在相对较短的传播距离上，湍流在确定脉冲塌陷的位置中也起着重要作用。
In a single shot, we measure the full propagation path, including the evolution to pulse collapse, of a high power femtosecond laser pulse propagating in air. This technique enables single-shot examination of the effect of parameters that fluctuate on a shot-to-shot basis, such as pulse energy, pulse duration, and air turbulence-induced refractive index perturbations. We find that even in lab air over relatively short propagation distances, turbulence plays a significant role in determining the location of pulse collapse.
