SUMMARY:GTIIT-STU optics seminar
DESCRIPTION:Title: Perturbative and non-perturbative light-matter interaction involving spatially structured light beams\nSpeaker: Bikash Kumar Das (GTIIT)\nAbstract\nIn this talk, I will present our recent works on both nonlinear perturbative [1] (specifically on second harmonic generation) and non-perturbative processes driven by spatially structured light beams. In particular, I will discuss how the utilization of the perfect optical vortex (POV) beams as a pump can remove some of the constraints imposed on the gas-phase high harmonic generation (HHG) driven by Laguerre-Gaussian (LG) vortex beams [2]. Later, I will discuss how we extended our theoretical model from the gas-phase HHG to the solid-state HHG realm to describe the formation of high harmonic vortices from ZnO [3], and the possibility of generating a twisted attosecond pulse train [4].\n\nKumar Das, M.
