Technical design report of a complete and compact broadband high-harmonics femtosecond beamline based on a modular hollow waveguide for photons generation centered on the upper region of the extreme ultraviolet spectral range
Yohann Brelet, Arnaud Marquette, Nicolas Beyer +5
We have successfully developed and implemented an entire and compact table-top high-order harmonics generation (HHG) setup from monochromatic and intense femtosecond ( s)…
Role of intersublattice exchange interaction on ultrafast longitudinal and transverse magnetization dynamics in Permalloy
A. Maghraoui, F. Fras, M. Vomir +4
We report about element specific measurements of ultrafast demagnetization and magnetization precession damping in Permalloy (Py) thin films. Magnetization dynamics induced by opti…
Underwater acoustic wave generation by filamentation of terawatt ultrashort laser pulses
Vytautas Jukna, Amelie Jarnac, Carles Milián +9
Acoustic signals generated by filamentation of ultrashort TW laser pulses in water are characterized experimentally. Measurements reveal a strong influence of input pulse duration…
Two-color interferometer for the study of laser filamentation triggered electric discharges in air
Guillaume Point, Yohann Brelet, Leonid Arantchouk +4
We present a space and time resolved interferometric plasma diagnostic for use on plasmas where neutral-bound electron contribution to the refractive index cannot be neglected. By…
Superfilamentation in air
Guillaume Point, Yohann Brelet, Aurélien Houard +6
The interaction between a large number of laser filaments brought together using weak external focusing leads to the emergence of few filamentary structures reminiscent of standard…
Effect of input pulse chirp on nonlinear energy deposition and plasma excitation in water
C. Milián, A. Jarnac, Y. Brelet +4
We analyze numerically and experimentally the effect of the input pulse chirp on the nonlinear energy deposition from J fs-pulses at nm to water. Numerical results are…
Lasing of ambient air with microjoule pulse energy pumped by a multi terawatt IR femtosecond laser
Guillaume Point, Yi Liu, Yohann Brelet +4
We report on the lasing action of atmospheric air pumped by an 800 nm femtosecond laser pulse with peak power up to 4 TW. Lasing emission at 428 nm increases rapidly over a small r…
Self-seeded lasing in ionized air pumped by 800 nm femtosecond laser pulses
Yi Liu, Yohann Brelet, Guillaume Point +2
We report on the lasing in air and pure nitrogen gas pumped by a single 800 nm femtosecond laser pulse. Depending on gas pressure, incident laser power and beam convergence, differ…
