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…

Subpicosecond dynamics of pre-plasma on a solid, formed by a ultra-high contrast, relativistic intensity pulse
Ankit Dulat, C. Aparajit, Anandam Choudhary +3
Using spectral interferometry technique, we measured subpicosecond time-resolved pre-plasma scale lengths and early expansion ( 12 ps) of the plasma produced by a high intensity…
