Terahertz emission from laser-driven gas-plasmas: a plasmonic point of view
I. Thiele, B. Zhou, A. Nguyen +8
We disclose an unanticipated link between plasmonics and nonlinear frequency down-conversion in laser-induced gas-plasmas. For two-color femtosecond pump pulses, a plasmonic resona…
Filamentation of ultrashort laser pulses in silica glass and KDP crystal: A comparative study
Jérémie Rolle, Luc Bergé, Guillaume Duchateau +1
Ionizing 800-nm femtosecond laser pulses propagating in silica glass and in potassium dihydrogen phosphate (KDP) crystal are investigated by means of a unidirectional pulse propaga…
On the Saturation of the Nonlinear Refractive Index in Atomic Gases
Christian Köhler, Roland Guichard, Emmanuel Lorin +4
Motivated by the ongoing controversy on the origin of the nonlinear index saturation and subsequent intensity clamping in femtosecond filaments, we study the atomic nonlinear polar…
