Quasi-static transverse electric field driven electron acceleration in relativistic laser matter interaction

Ameya Parab, Bhooshan Paradkar, Aparajit C. +4

The paper demonstrates that a quasi‑static transverse electric field, aligned with the laser polarization plane, can reduce dephasing and boost energy gain in laser‑driven relativi…

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…

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…

Spatial, Spectral and Temporal Response of High Intensity Laser Plasma Mirrors- Direct Observation of the Ponderomotive Push

Sk Rakeeb, Animesh Sharma, Sagar Dam +5

Plasma-based optics have emerged as a powerful platform for manipulating and amplifying ultra-intense laser pulses. However, the inherently nonlinear and dynamic nature of plasma l…

Impulsive excitation of a solid by extreme contrast, high intensity femtosecond laser pulses

Sagar Dam, Jian Fuh Ong, Sk Rakeeb +8

We present the ultra-fast dynamics of the interaction between a high-intensity extreme contrast (expected to be around 1e-18 at hundreds of picoseconds timescale) femtosecond laser…

10-fold amplification of a tiny magnetic field to megagauss scale in femtosecond, ultraintense laser-solid interaction

Anandam Choudhary, Trishul Dhalia, Sagar Dam +8

Generating a powerful and quasistatic magnetic field within the confines of a tabletop laboratory experiment has proven to be a persistent challenge. The creation of magnetized hig…
