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…
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…
Intrinsic femtosecond structure of extreme contrast harmonic pulses: influence on relativistic laser-solid interactions
C. Aparajit, Anandam Choudhary, Ankit Dulat +7
Extreme intensity contrast is considered essential for ultraintense, femtosecond laser excitation of solid targets, in particular for studies with structured or ultra-thin targets.…
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…
Controlling intense, ultrashort, laser-driven relativistic mega-ampere electron fluxes by a modest, static magnetic field
Anandam Choudhary, Trishul Dhalia, C. Aparajit +6
The guiding and control of ultrahigh flux, femtosecond relativistic electron pulses through solid density matter is of great importance for many areas of high energy density scienc…
Single-Shot, Spatio-Temporal Metrology of Relativistic Plasma Optics
Ankit Dulat, Amit D. Lad, C. Aparajit +4
Ultrahigh peak power femtosecond laser pulses create extreme states of matter that are currently being probed with great interest. Plasma optics have been proposed for shaping and…
