TL;DR: The effects of wavelength, pulse power, intensity, propagation length, and crystallinity on supercontinuum and high harmonic generation are investigated experimentally using ultrafast mid-infrared pulses, finding harmonic conversion efficiency scales linearly in propagation length.
Journal ArticleDOI
High-repetition-rate ( kHz) targets and optics from liquid microjets for high-intensity laser–plasma interactions
Kevin George,J. T. Morrison,S. Feister,G. K. Ngirmang,Joseph Smith,Adam Klim,Joseph Snyder,Drake R. Austin,Wes Erbsen,Kyle Frische,John Nees,Chris Orban,Enam Chowdhury,William M. Roquemore +13 more
TL;DR: In this article, a high-repetition-rate laser-plasma interaction with liquid microjets is demonstrated using pump-probe shadowgraphy to evaluate their use as targets.
Journal ArticleDOI
Time-resolved measurement of single pulse femtosecond laser-induced periodic surface structure formation induced by a pre-fabricated surface groove.
TL;DR: A 1-D analytical model of electron heating including both the laser pulse and surface plasmon polariton excitation at the groove edge predicts ripple period, melt spot diameter, and qualitatively explains the asynchronous time-evolution of LIPSS formation.
Journal ArticleDOI
Laser induced periodic surface structure formation in germanium by strong field mid IR laser solid interaction at oblique incidence
Drake R. Austin,Kyle Kafka,Simeon Trendafilov,Gennady Shvets,Hui Li,Allen Y. Yi,Urszula B. Szafruga,Zhou Wang,Yu Hang Lai,Cosmin I. Blaga,Louis F. DiMauro,Enam Chowdhury +11 more
TL;DR: A vector model of SPP coupling is introduced to explain the formation of s-polarized LSFL away from the center of the damage spot and a new method is proposed to determine the SPP propagation length from the decay in ripple depth.
