Relativistic electron dynamics in ultra-intense lasers
Amol R Holkundkar
These lectures at Winter School on Intense Laser Science (WiSILS-2024) at IIT Jodhpur, India, will focus on the Relativistic charge particle dynamics in ultra-intense laser pulses.…
Complete characterization of ultra-intense laser pulses in radiation damping regime
Amol R. Holkundkar, Felix Mackenroth
We report the first closed, analytical expression for the scattering angle of an electron bunch ponderomotively scattered from a counter-propagating, ultra-intense laser pulse, als…
Dispersion of the laser pulse through propagation in underdense plasmas
Shivani Choudhary, Amol R. Holkundkar
The propagation of the laser pulses in the underdense plasma is a very crucial aspect of laser-plasma interaction process. In this work, we explored the two regimes of laser propag…
Chirp assisted ion acceleration via relativistic self induced transparency
Shivani Choudhary, Amol R. Holkundkar
We study the effect of the chirped laser pulse on the transmission and associated ion acceleration by the sub-wavelength target. In the chirped laser pulses, the pulse frequency ha…
Transition from wakefield generation to soliton formation
Amol R. Holkundkar, Gert Brodin
It is well known that when a short laser pulse propagates in an underdense plasma, it induces longitudinal plasma oscillations at the plasma frequency after the pulse, typically re…
Focussing effects in laser-electron Thomson scattering
C. Harvey, M. Marklund, A. R. Holkundkar
We study the effects of laser pulse focussing on the spectral properties of Thomson scattered radiation. Modelling the laser as a paraxial beam we find that, in all but the most ex…
Effects of cluster size and spatial laser intensity distribution on fusion neutron generation by laser driven Deuterium clusters
Gaurav Mishra, Amol R. Holkundkar
A three dimensional molecular dynamic code is used to study the generation of fusion neutrons from Coulomb explosion of Deuterium clusters driven by intense near infra-red (NIR) la…
Thomson scattering in high-intensity chirped laser pulses
Amol R. Holkundkar, Chris Harvey, Mattias Marklund
We consider the Thomson scattering of an electron in an ultra-intense chirped laser pulse. It is found that the introduction of a negative chirp means the electron enters a high fr…
Ion acceleration 'via' relativistic self induced transparency in subwavelength target
Shivani Choudhary, Amol R. Holkundkar
In this work we have studied the effect of target thickness on relativistic self-induced transparency (RSIT) and found out that for subwavelength targets the corresponding threshol…
Particle-in-Cell simulations of electron spin effects in plasmas
G. Brodin, A. Holkundkar, M. Marklund
We have here developed a particle-in-cell code accounting for the magnetic dipole force and for the magnetization currents associated with the electron spin. The electrons is divid…
Wakefield generation in magnetized plasmas
A. Holkundkar, G. Brodin, M. Marklund
We consider wakefield generation in plasmas by electromagnetic pulses propagating perpendicular to a strong magnetic field, in the regime where the electron cyclotron frequency is…
