Single attosecond XUV pulse source via light-wave controlled relativistic laser-plasma interaction: Thomson Back Scattering Scheme
Mojtaba Shirozhan, Fabien Quéré, Subhendu Kahaly
Reflecting light off a mirror moving near light speed offers a powerful method for generating bright, ultrashort pulses in the extreme ultraviolet range. Several investigations sho…
Controlled transition to different proton acceleration regimes: near-critical density plasmas driven by circularly polarized few cycle pulse
Shivani Choudhary, Sudipta Mondal, Daniele Margarone +1
We investigate the different facets of ion acceleration by a relativistically intense circularly polarized laser pulse interacting with thin near-critical density plasma targets. O…
Persistence of magnetic field driven by relativistic electrons in a plasma
A. Flacco, J. Vieira, A. Lifschitz +5
The onset and evolution of magnetic fields in laboratory and astrophysical plasmas is determined by several mechanisms, including instabilities, dynamo effects and ultra-high energ…
Short Intense Laser Pulse Collapse in Near-Critical Plasma
F. Sylla, A. Flacco, S. Kahaly +5
It is observed that the interaction of an intense ultra-short laser pulse with an overdense gas jet results in the pulse collapse and the deposition of a significant part of energy…
Anticorrelation between Ion Acceleration and Nonlinear Coherent Structures from Laser-Underdense Plasma Interaction
F. Sylla, A. Flacco, S. Kahaly +5
In laser-plasma experiments, we observed that ion acceleration from the Coulomb explosion of the plasma channel bored by the laser, is prevented when multiple plasma instabilities…
Sub-lambda gratings, surface plasmons, hotter electrons and brighter x-ray sources- enhanced absorption of intense, ultrashort laser light by tiny surface modulations
Subhendu Kahaly, G. Ravindra Kumar
We observe near 100 % absorption of light in intense ultrashort laser plasma interaction in a metal coated (Au on glass) sub-lambda grating structure under suitable conditions and…
