摘要

只提供摘要形式。在3 + 1维克尔非线性自聚焦模型中表明,群速度色散是超短脉冲在传播过程中产生时间脉冲分裂的主要原因。先前的实验已经证明了短脉冲在块状或气体介质中传播时由于克尔非线性引起的脉冲分裂。然而,对气体介质的研究通常是聚焦几何,或使用加压气体介质。该实验阐明了脉冲分裂与光斑大小变化之间的关系,并且没有使用任何光学元件来启动自聚焦。我们发现脉冲分裂发生在距离仅为0.7/spl倍/衍射长度处,并且发生在空间坍缩成细丝之前。此外,还观察到多脉冲分裂现象。监测来自光束剖面的峰值流量信息,指示非线性损失机制。我们认为这是第一个关于空气中多重脉冲分裂事件的数据。

Observation of multiple pulse-splitting of ultrashort pulses in air
Summary form only given. It has been shown in 3 + 1 dimensional Kerr-nonlinearity self-focusing models, that group velocity dispersion is responsible for the temporal pulse-splitting of ultrashort pulses during propagation. Previous experiments have demonstrated pulse splitting due to the Kerr nonlinearity for short pulse propagation in bulks or gaseous media. However, studies in gaseous media are often in a focused geometry, or use pressurized gaseous media. This experiment elucidates the relationship between pulse splitting and spot-size change and does not use any optic to initiate self-focusing. We find pulse splitting occurs at a distance merely 0.7/spl times/ the diffraction length and occurs before spatial collapse to a filament. In addition, multiple pulse splitting is also observed. Peak fluence information from the beam-profile is monitored, indicating nonlinear loss mechanisms. We believe this is the first data on multiple pulse-splitting events in air.
