Quasi-static transverse electric field driven electron acceleration in relativistic laser matter interaction
Ameya Parab, Bhooshan Paradkar, Aparajit C. +4
Achieving significant energy gain in laser-driven relativistic electron beams remains challenging due to dephasing between the accelerating laser field and the electrons. We show t…

Tens of MeV, collimated, bright fluxes of protons from ordered nano-structured targets in ultra-relativistic laser-matter interaction
Sagar Dam, Stefania Ionescu, Jian Fuh Ong +20
Laser-driven proton acceleration from nanostructured solid targets has been extensively studied, yet its performance under realistic temporal contrast conditions at petawatt-class…

Caustic-Driven Fluidic Microlenses for Enhanced Nonlinear and High-Energy-Density Physics
Sourabh Singh, S. Sree Harsha, Tamanna +1
We demonstrate that caustic microlensing occurring in a liquid jet efficiently drives linear, nonlinear, and high-energy-density phenomena. In the linear regime, caustics provide l…
