Alloharmonics in Burst Intensification by Singularity Emitting Radiation
K. Ogura, M. S. Pirozhkova, A. Sagisaka +18
Burst Intensification by Singularity Emitting Radiation (BISER) in underdense relativistic laser plasma is a bright source of coherent extreme ultraviolet (XUV) and x-ray radiation…
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…
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…
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,…
