Tracing spatial confinement in semiconductor quantum dots by high-order harmonic generation
H. N. Gopalakrishna, R. Baruah, C. Hünecke +20
We report here on results of experimental-theoretical investigation of high-order harmonic generation (HHG) in layers of CdSe semiconductor quantum dots of different sizes and a re…
Ionization rate and plasma dynamics at 3.9 micron femtosecond photoionization of air
Adam Patel, Claudia Gollner, Rokas Jutas +5
The introduction of mid-IR optical parametric chirped pulse amplifiers (OPCPAs) has catalyzed interest in multi-millijoule, infrared femtosecond pulse-based filamentation. As tunne…
Simple approach for extending the ambiguity-free-range of dual-comb ranging
Jakob Fellinger, Georg Winkler, P. E. Collin Aldia +8
Dual-comb (DC) ranging is an established method for high-precision and high-accuracy distance measurements. It is, however, restricted by an inherent length ambiguity and the requi…
Relativistic interaction of long-wavelength ultrashort laser pulses with nanowires
Z. Samsonova, S. Höfer, V. Kaymak +11
We report on experimental results in a new regime of a relativistic light-matter interaction employing mid-infrared (3.9-micrometer wavelength) high-intensity femtosecond laser pul…
Filamentation of Mid-IR pulses in ambient air in the vicinity of molecular resonances
Valentina Shumakova, Skirmantas Alisauskas, Pavel Malevich +8
Properties of filaments ignited by multi-millijoule, 90-fs mid-IR pulses centered at 3.9 μm are examined experimentally by monitoring plasma density and losses as well as spectral…
Laser wakefield acceleration with mid-IR laser pulses
D. Woodbury, L. Feder, V. Shumakova +8
We report on the first results of laser plasma wakefield acceleration driven by ultrashort mid-infrared laser pulses (λ= 3.9 μm, 100 fs, 0.25 TW), which enable near- and above-crit…
Conductivity and Discharge Guiding Properties of Mid-IR Laser Filaments
Denis Mongin, Valentina Shumakova, Skirmantas Ališauskas +5
The electric conductivity, HV discharge triggering and guiding capabilities of filaments at 3.9 micrometer in air are investigated in the perspective of lightning control applicati…
