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…
Quasi mono-energetic, relativistic electron acceleration in a femtosecond, high intensity laser excited solid magnet
Trishul Dhalia, Anandam Choudhary, C. Aparajit +6
The interaction of ultraintense lasers with magnetized overdense plasmas reveals a fundamentally new regime of laser-driven particle acceleration. Particle-in-cell simulations demo…
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…
Generation of mega-gauss axial and azimuthal magnetic fields in a solid plasma by ultrahigh intensity, circularly polarised femtosecond laser pulses
Anandam Choudhary, Laxman Prasad Goswami, C. Aparajit +5
The interaction of intense linearly polarized femtosecond laser pulses with solids is known to generate azimuthal magnetic fields, while circularly polarized light has been shown t…
