Ultrashort Laser-Plasma Solitons

功率在太瓦的台式激光系统使得在大学环境中研究高强度激光等离子体相互作用成为可能。本研究项目的目标是通过实验确定一种可以产生超短激光等离子体孤子的体制。这样的孤子，在高强度下产生时，预计会以不变的脉冲持续时间和形状传播很远的距离，而在低强度下，会导致脉冲的时间拉伸。该研究将试图证明超短激光脉冲可以作为时间孤子传播，并通过改变实验条件来研究这种孤子的稳定性。

Tabletop laser systems with powers in the terawatt regime have made it possible to study high intensity laser-plasma interactions within a university environment. The goal of this research project is to identify experimentally a regime in which ultrashort laser-plasma solitons can be created. Such solitons, when created at high intenstities, are predicted to propagate with unchanging pulse duration and shape for distances large compared to those which, at low intensity, would result in the temporal stretching of the pulse. The research will seek to demonstrate that ultrashort laser pulses can propagate as temporal solitons and to investigate the stability of such solitons by varying the experimental conditions.
