- Abstract
In this paper, the relativistic electromagnetic 1.5 dimensional particle-in-cell code has been employed to investigate the temporal behavior of nonlinear absorption of a short intense laser pulse in finite-size magnetized sub-critical (i.e. under the critical density) plasma. This work has been done by relying on a detailed temporal study of the phase-mixing and scattering processes occurring in the finite-size system of laser-plasma interaction. Part of the results obtained in this manuscript confirm recent important theoretical findings, including the wave-breaking or phase-mixing phenomena of relativistic upper-hybrid (UH) oscillations in magnetized plasma [C. Maity, A. Sarka, P.K. Shukla, N. Chakrabarti, Phys. Rev. Lett. 110, 215002 (2013)]. Moreover, we found the explicit reasons for the anomalous behavior of the absorption rate in magnetized plasma by scrutinising the phase-mixing time and scattering process in finite-size magnetized plasma for different values of laser and plasma parameters.
