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…

Soft X-ray harmonic comb from relativistic electron spikes
A. S. Pirozhkov, M. Kando, T. Zh. Esirkepov +37
We demonstrate a new high-order harmonic generation mechanism reaching the `water window' spectral region in experiments with multi-terawatt femtosecond lasers irradiating gas jets…

X-ray harmonic comb from relativistic electron spikes
Alexander S. Pirozhkov, Masaki Kando, Timur Zh. Esirkepov +24
X-ray devices are far superior to optical ones for providing nanometre spatial and attosecond temporal resolutions. Such resolution is indispensable in biology, medicine, physics,…
