Terahertz generation via all-optical quantum control in 2D and 3D materials
Kamalesh Jana, Amanda B. B. de Souza, Yonghao Mi +6
Using optical technology for current injection and electromagnetic emission simplifies the comparison between materials. Here, we inject current into monolayer graphene and bulk ga…
Mapping the complete evolution of magnetic excitation in beam-plasma system driven by an ultra-intense, femtosecond laser
Moniruzzaman Shaikh, Amit D Lad, Devshree Mandal +4
Plasmas are beset with instabilities of all types, hydrodynamic, magneto-hydrodynamic, and electromagnetic. These instabilities are complex, occur over a large range of temporal an…
Flying doughnut terahertz pulses generated from semiconductor currents
Kamalesh Jana, Yonghao Mi, Søren H. Møller +5
The ability to manipulate the space-time structure of light waves diversifies light-matter interaction and light-driven applications. Conventionally, metasurfaces are employed to l…
Collimated hot electron generation from sub-wavelength grating target irradiated by a femtosecond laser pulse of relativistic intensity
Kamalesh Jana, Amit D. Lad, Guo-Bo Zhang +6
We investigate the production of hot electrons from the interaction of relativistically intense () ultra-short (25 fs) laser pulses with sub-wavelength grating…
Mapping the direction of electron ionization to phase delay between VUV and IR laser pulses
M. Mountney, G. P. Katsoulis, S. H. Møller +3
We theoretically demonstrate a one-to-one mapping between the direction of electron ionization and the phase delay between a linearly polarized VUV and a circular IR laser pulse. T…
Efficient second-harmonic generation of a high-energy, femtosecond laser pulse in a lithium triborate (LBO) crystal
C. Aparajit, Kamalesh Jana, Amit D. Lad +3
We demonstrate the highest efficiency (80%) second harmonic generation (SHG) of Joule level, 27 femtosecond, high contrast pulses in a type-I lithium triborate (LBO) crystal.…
Macroscopic, layered onion shell like magnetic domain structure generated in YIG film using ultrashort, megagauss magnetic pulses
Kamalika Nath, P. C. Mahato, Moniruzzaman Shaikh +6
Study of the formation and evolution of large scale, ordered structures is an enduring theme in science. The generation, evolution and control of large sized magnetic domains are i…
Generation of a strong reverse shock wave in the interaction of a high-contrast high-intensity femtosecond laser pulse with a silicon target
Kamalesh Jana, Amit D. Lad, Moniruzzaman Shaikh +6
We present ultrafast pump-probe reflectivity and Doppler spectrometry of a silicon target at relativistic laser intensity. We observe an unexpected rise in reflectivity to a peak a…
