Micrometer-thin liquid sheets from single-jet impact on a sharp edge for multi-kHz laser-plasma experiments
Mukesh Kumar, S. Sree Harsha, Prashant Kumar Singh
We present a simple and robust method for generating freely suspended liquid sheets by directing a single laminar liquid jet onto the sharp edge of an inclined plate. By optimizing…
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…
Bright, directional electron emission from nanowire coated targets under petawatt, femtosecond irradiation
Ameya Parab, Jian Fuh Ong, Stefania Ionescu +13
Interactions of relativistically intense laser pulses with structured targets have long been explored for controlling energy absorption and particle acceleration. However, at upcom…
