DESCRIPTION:LINK(+)Structured light - light whose spatial and temporal pro
 files may be simultaneously tailored - offers new capabilities for control
 ling all degrees of freedom of an optical field and\, therefore\, its inte
 raction with matter. Achieving such control requires tunable spatiotempora
 l spectra. In this talk\, I present a comprehensive framework for structur
 ed light\, encompassing theory\, numerical modelling\, and experimental wo
 rk.First\, I derive methods for accurately controlling the focal trajector
 y of wave packets and outline a numerical framework for injecting arbitrar
 y structured light into FDTD codes. Next\, I explore the generation of spa
 tiotemporally structured radiation through laser-plasma interactions. To t
 his end\, I introduce a generalised Thomson scattering formalism that enab
 les the design of experiments for creating tailored spatiotemporal pulses.
  Finally\, I present experimental and simulation results regarding &quot\;
 light springs&quot\;\, demonstrating their synthesis and spectral measurem
 ents\, as well as their application in tuning orbital group velocity for p
 lasma super-radiance.
