High-order alloharmonics produced by nonperiodic drivers
M. S. Pirozhkova, K. Ogura, A. Sagisaka +18
High-order harmonics are ubiquitous in nature and present in electromagnetic, acoustic, and gravitational waves. They are generated by periodic nonlinear processes or periodic high…
Nonlinear propagation effect in x-ray parametric amplification during high harmonic generation
J. Seres, E. Seres, C. Serrat +6
We report the realization and characterization of parametric amplification in high harmonic generation around 100 eV using He gas in a double gas jet arrangement. The delay of the…
Parametric attosecond pulse amplification far from the ionization threshold from high order harmonic generation in He
C. Serrat, J. Seres, E. Seres +4
Parametric amplification of attosecond coherent pulses around 100 eV at the single-atom level is demonstrated for the first time by using the 3D time-dependent Schr{ö}dinger equati…
Effect of plasma formation on the double pulse laser excitation of cubic silicon carbide
T. Otobe, T. Hayashi, M. Nishikino
We calculate the electron excitation in cubic silicon carbide (3C-SiC) caused by the intense femtosecond laser double pulses using time-dependent density functional theory (TDDFT).…
Burst intensification by singularity emitting radiation in multi-stream flows
A. S. Pirozhkov, T. Zh. Esirkepov, T. A. Pikuz +20
In various media the elementary components can emit traveling waves such as electromagnetic, gravitational or acoustic types. If these elementary emitters are synchronized, the res…
Prepulse and amplified spontaneous emission effects on the interaction of a petawatt class laser with thin solid targets
Timur Zh. Esirkepov, James K. Koga, Atsushi Sunahara +17
When a finite contrast petawatt laser pulse irradiates a micron-thick foil, a prepulse (including amplified spontaneous emission) creates a preplasma, where an ultrashort relativis…
Spallative ablation of dielectrics by X-ray laser
N. A. Inogamov, V. V. Zhakhovsky, A. Ya. Faenov +15
Short laser pulse in wide range of wavelengths, from infrared to X-ray, disturbs electron-ion equilibrium and rises pressure in a heated layer. The case where pulse duration …
