Description

Despite piquing interest in the intense laser-plasma community during the past several decades, monitoring the spatio-temporal evolution of megagauss magnetic fields continues to provide a window to the dynamics of hot electron transport, pivotal to ion acceleration schemes. Besides, these magnetic fields mirror the plethora of electromagnetic waves and instabilities, coupled with the disparate behaviours of electrons and ions, and thereby serve as a table-top platform for scaled laboratory replications of diverse astrophysical scenarios. Some recent results in this context [1-2] will be discussed, along with a brief description of our ongoing efforts [3,4] towards novel laser architectures involving sub-mJ-level, $\sim$100 fs optical parametric chirped pulse amplifiers (OPCPAs) in the mid-infrared (>5 $\mu$m) for potential applications in efficient high-harmonic generation and hard X-ray plasma sources.
