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…
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…
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,…
Novel path towards compact laser ion accelerators for hadron therapy: Tenfold energy increase in laser-driven multi-MeV ion generation using a gas target mixed with submicron clusters
Y. Fukuda, A. Ya. Faenov, M. Tampo +20
We demonstrate generation of 10-20 MeV/u ions with a compact 4 TW laser using a gas target mixed with submicron clusters, corresponding to tenfold increase in the ion energies comp…
Coulomb implosion mechanism of negative ion acceleration in laser plasmas
T. Nakamura, Y. Fukuda, A. Yogo +10
Coulomb implosion mechanism of the negatively charged ion acceleration in laser plasmas is proposed. When a cluster target is irradiated by an intense laser pulse and the Coulomb e…
