Coherence effects in LIPSS formation on silicon wafers upon picosecond laser pulse irradiations
Inam Mirza, Juraj Sládek, Yoann Levy +7
Using different laser irradiation patterns to modify of silicon surface, it has been demonstrated that, at rather small overlapping between irradiation spots, highly regular laser-…

Narrowband gamma-ray radiation generation by acoustically driven crystalline undulators
Konstantinos Kaleris, Evaggelos Kaselouris, Vasilios Dimitriou +7
In this paper we present a novel scheme for the controlled generation of of tunable narrowband gamma-ray radiation by ultra-relativistic positron beams inside acoustically driven p…
