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…
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…
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…
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…
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…
Capturing the three dimensional, nano-scale, pico-second dynamics of plasma mirrors with intense ultrashort laser wavefront measurement
Sk Rakeeb, Sagar Dam, Ameya Parab +3
We present a direct measurement of the nanoscale dynamics of plasma mirrors using wavefront measurement techniques. This two-dimensional measurement, performed via pump-probe diagn…
Femtosecond dynamics on the nanoscale of intense laser-induced grating plasma
Ankit Dulat, Sagar Dam, Sk Rakeeb +3
The complex interaction dynamics of intense femtosecond (fs) pulses and their picosecond (ps)-long leading edge with nanostructured solids occur at both the nanometer and the femto…
Coherent Control of Relativistic Electron Dynamics in Plasma Nanophotonics
Ankit Dulat, Sk Rakeeb, Sagar Dam +4
Intense femtosecond laser pulses interacting with solids can drive electrons to relativistic energies, enabling miniaturized particle accelerators and bright extreme-ultraviolet li…
