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…
Pushing the Frontiers of Light: Magnetized Plasma Lenses and Chirp Tailoring for Extreme Intensities
Trishul Dhalia, Rohit Juneja, Amita Das
In this work, an innovative scheme is proposed that exploits the response of magnetized plasmas to realize a refractive index exceeding unity for right circularly polarized (RCP) w…
Electron heating in bulk overdense plasma aided by time dependent external magnetic field
Rohit Juneja, Trishul Dhalia, Amita Das
This study investigates the localized electron heating in a bulk overdense plasma. The method relies on using a time dependent magnetic field. An initially high external magnetic f…
Laser pulse focusing and energetic electron generation by magnetized plasma lens
Trishul Dhalia, Rohit Juneja, Amita Das
An efficient mechanism of laser pulse focusing with the help of shaped underdense plasma target immersed in inhomogeneous magnetic field has been demonstrated. These studies have b…
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…
Chaos aided regime of Laser/Electromagnetic Energy Absorption by plasma
Rohit Juneja, Amita Das, Trishul Dhalia +1
The absorption of laser energy by plasma is of paramount importance for various applications. Collisional and resonant processes are often invoked for this purpose. However, in som…
