Wavelength scaling of electron collision time in plasma for strong field laser-matter interactions in solids

[摘要] Understanding self-guiding propagation of laser filaments relies on understanding of the fundamental light-matter interactions, and the optical properties of the plasma. The authors experimentally and theoretically study wavelength scaling of the electron collision time in filament-produced plasma using 1.2-2.3 micrometers and demonstrate an anomalous regime of plasma defocusing in solids.
